MSL1060AW-R LED Driver IC Equivalent & Substitute Parts

Part Overview

The MSL1060AW-R is a 6-output LED driver IC with integrated DC-DC Step-Up (Boost) regulator topology, manufactured by Microchip Technology. This device is classified as obsolete, making equivalent and substitute parts necessary for new designs and production continuity. The MSL1060AW-R operates across a 4.75V to 36V supply range with 48V output capability and supports both analog and PWM dimming at 30mA per channel. Substitute parts must maintain functional equivalence in LED driver topology, output configuration, and dimming control while accommodating variations in electrical specifications and packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSL1060AW-R is determined by the following critical parameters:

• Topology: Step-Up (Boost) regulator with integrated LED driver functionality
• Output Configuration: 6-output LED driver with independent channel control
• Dimming Control: PWM and/or analog dimming capability
• Supply Voltage Range: Minimum 4.75V input compatibility
• Output Voltage: Capability to reach or exceed 48V
• Current per Channel: Minimum 30mA output current per LED channel
• Switching Frequency: Operation in the 600kHz to 1.3MHz range
• Package Type: Surface mount with exposed pad thermal management
• Compliance: ROHS3 compliance and EAR99 classification

The substitute parts listed below maintain functional equivalence in LED driver topology and dimming control. Variations in supply voltage range, output voltage capability, current rating, and package form factor are acceptable provided the substitute meets or exceeds the minimum electrical requirements for the target application.

Engineering Selection Recommendations

ISL97671AIRZ-TK (Renesas Electronics): Active product status with 6-output configuration matching the MSL1060AW-R. Supports 50mA per channel, exceeding the 30mA requirement. Supply voltage range 4.5V to 26.5V accommodates the primary operating window. Output voltage of 45V approaches the 48V specification. PWM dimming control is supported. ROHS3 compliant with MSL3 rating. Suitable for designs requiring higher current capability and active manufacturer support.

LM3633YFQR (Texas Instruments): Active product with 6-output configuration and dual topology (Step-Up and Switched Capacitor). Operates across 2.7V to 5.5V supply range, providing extended low-voltage capability. Output voltage of 40V is below the 48V target but acceptable for reduced-voltage applications. Current rating of 30mA matches the original specification. PWM dimming supported. MSL1 rating provides superior moisture handling. Operating temperature extends to 125°C (TJ). Suitable for low-voltage backlight applications with extended thermal range.

LP8556TME-E06/NOPB (Texas Instruments): Active product with 5-output configuration (one fewer output than the original). Supports 50mA per channel with programmable output voltage range of 7V to 43V. Supply voltage range 2.7V to 20V. MSL1 rating and unlimited moisture sensitivity. Suitable for applications where 5 outputs are sufficient and lower supply voltage operation is required.

TPS61182RTER (Texas Instruments): Active product with 6-output configuration. Current rating of 25mA is below the 30mA specification but within acceptable margin for reduced-brightness applications. Supply voltage range 5V to 24V. Output voltage of 38V is below 48V target. Smallest package footprint (16-WQFN) among substitutes. MSL2 rating. Suitable for space-constrained designs with moderate current requirements.

All substitute parts maintain ROHS3 compliance and EAR99 classification, ensuring regulatory equivalence with the original MSL1060AW-R.

Frequently Asked Questions (FAQ)

Q: Can the ISL97671AIRZ-TK directly replace the MSL1060AW-R in existing designs?

A: The ISL97671AIRZ-TK maintains 6-output LED driver topology and Step-Up regulator function. However, the package changes from 24-WQFN to 20-VFQFN, requiring PCB layout modification. Supply voltage range differs (4.5V to 26.5V vs. 4.75V to 36V), and output voltage is 45V instead of 48V. Schematic and layout redesign is necessary.

Q: Why does the LM3633YFQR have a lower maximum supply voltage than the MSL1060AW-R?

A: The LM3633YFQR is optimized for low-voltage backlight applications with a 2.7V to 5.5V supply range. This design choice enables extended temperature operation (-40°C to 125°C) and superior moisture sensitivity (MSL1). It is suitable for battery-powered and low-voltage systems but not for applications requiring the full 36V input capability of the MSL1060AW-R.

Q: Is the LP8556TME-E06/NOPB suitable as a substitute if the application requires 6 LED outputs?

A: The LP8556TME-E06/NOPB provides only 5 outputs compared to the 6-output requirement of the MSL1060AW-R. This part is suitable only for applications that can operate with 5 LED channels. For 6-channel applications, select ISL97671AIRZ-TK, LM3633YFQR, or TPS61182RTER.

Q: What is the impact of the TPS61182RTER's 25mA current rating versus the 30mA specification of the MSL1060AW-R?

A: The TPS61182RTER provides 25mA per channel, which is 83% of the original 30mA specification. This reduction may limit LED brightness or require design adjustment to accommodate lower current per channel. The part is suitable for applications where reduced brightness is acceptable or where LED current is externally limited.

Q: Are all substitute parts available in tape and reel packaging for production?

A: All substitute parts listed are available in Tape & Reel (TR) packaging suitable for automated assembly. Verify current inventory and lead times with component distributors before design commitment.

Q: Do all substitute parts support both analog and PWM dimming like the MSL1060AW-R?

A: The MSL1060AW-R supports both analog and PWM dimming. All substitute parts listed support PWM dimming. Analog dimming support is not specified for the substitute parts. If analog dimming is required, verify dimming control capability in the target part's datasheet before selection.

Q: What is the significance of the MSL (Moisture Sensitivity Level) rating differences?

A: MSL ratings indicate moisture sensitivity during storage and handling. MSL1 (unlimited) provides the most robust moisture tolerance, while MSL3 (168 hours) requires more controlled storage conditions. LM3633YFQR and LP8556TME-E06/NOPB offer MSL1 ratings, providing superior handling flexibility. TPS61182RTER has MSL2 (1 year), and ISL97671AIRZ-TK has MSL3, requiring stricter moisture control.
