MIC2282YMM LED Driver IC Equivalent & Substitute Parts

Part Overview

The MIC2282YMM is an active LED Driver IC manufactured by Microchip Technology, designed as a 1-output DC-DC Step-Up (Boost) regulator with internal switching capability. This component delivers 1.1A switch current and operates across a 0.9V to 15V supply range, producing up to 35V output. The device is housed in an 8-MSOP surface mount package and is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when design requirements necessitate alternative packaging, different thermal operating ranges, enhanced current handling, or modified topology configurations while maintaining core LED driver functionality.

Substitute Part Grouping Explanation

Substitution logic for the MIC2282YMM is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Device Type: DC-DC Regulator with LED Driver capability
• Topology: Step-Up (Boost) configuration with internal switching
• Number of Outputs: Single output
• Output Voltage Capability: Minimum 35V or higher
• Output Current: 1.1A or greater switch current
• Supply Voltage Range: Overlap with 0.9V to 15V input specification
• Surface Mount Packaging: Compatible with PCB assembly processes
• Product Status: Active manufacturing status
• Compliance: ROHS3 and REACH compliance maintained

The four identified substitute parts meet these criteria with variations in package form factor, switching frequency, dimming capability, and thermal operating range. Each substitute maintains the core boost regulator topology and LED driver functionality while offering alternative specifications for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

AP3602AKTR-G1 (Diodes Incorporated): This substitute is suitable for low-current LED driver applications requiring compact SOT-23-6 packaging. The 100mA output current and fixed 4.8V to 5.2V output voltage limit this part to backlight and camera flash applications with reduced power requirements compared to the MIC2282YMM. MSL rating of 3 requires controlled storage conditions.

LT3478EFE#PBF (Analog Devices Inc.): This substitute offers enhanced current handling at 4.5A and extended output voltage capability to 42V, supporting higher-power LED driver applications. The dual topology (Buck-Boost) and PWM dimming capability provide additional design flexibility. Extended operating temperature range to 125°C (TJ) and 16-TSSOP-EP packaging with exposed pad support thermal management in demanding environments. Unlimited MSL rating ensures standard storage conditions.

NCV3065DR2G (onsemi): This substitute provides 1.5A output current with dual topology (Buck-Boost) and both analog and PWM dimming options. The 8-SOIC package offers a footprint alternative to the MIC2282YMM's 8-MSOP. Extended supply voltage range to 40V and operating temperature to 125°C (TJ) support industrial lighting applications. Unlimited MSL rating and active product status ensure long-term availability.

TPS61046YFFR (Texas Instruments): This substitute is optimized for low-input-voltage boost applications with 1.8V minimum supply voltage and adjustable output from 4.5V to 28V. The 1.2A output current and 1.05MHz switching frequency provide efficient power conversion in portable and battery-powered LED driver circuits. 6-DSBGA package offers space-constrained design options. Extended operating temperature to 125°C (TJ) and unlimited MSL rating support diverse applications.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and active product status, ensuring regulatory compliance and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can AP3602AKTR-G1 directly replace MIC2282YMM in high-current LED applications?

A: No. The AP3602AKTR-G1 is rated for 100mA output current versus the MIC2282YMM's 1.1A. This substitute is limited to low-power backlight and camera flash applications and cannot support applications requiring the full 1.1A output current of the original part.

Q: What is the primary advantage of LT3478EFE#PBF over MIC2282YMM?

A: The LT3478EFE#PBF provides 4.5A output current, dual Buck-Boost topology, PWM dimming capability, and extended operating temperature to 125°C (TJ). These features support higher-power LED driver designs and industrial temperature environments. The 16-TSSOP-EP package with exposed pad enables superior thermal management.

Q: Are there package compatibility considerations when substituting NCV3065DR2G for MIC2282YMM?

A: Yes. The NCV3065DR2G uses 8-SOIC packaging versus the MIC2282YMM's 8-MSOP. While both are 8-pin surface mount packages, the pin pitch and footprint differ. PCB layout modifications are required for direct substitution.

Q: Which substitute part is best for battery-powered LED driver circuits?

A: The TPS61046YFFR is optimized for battery-powered applications with a minimum input voltage of 1.8V, supporting single-cell lithium or multi-cell alkaline battery configurations. The adjustable output voltage range (4.5V to 28V) accommodates various LED string configurations.

Q: Do all substitute parts maintain the same moisture sensitivity level as MIC2282YMM?

A: No. The MIC2282YMM and three substitutes (LT3478EFE#PBF, NCV3065DR2G, TPS61046YFFR) have MSL rating 1 (Unlimited). The AP3602AKTR-G1 has MSL rating 3 (168 Hours), requiring controlled storage and handling procedures.

Q: What is the switching frequency difference between MIC2282YMM and its substitutes?

A: The MIC2282YMM operates at 20kHz. Substitutes range from 150kHz (NCV3065DR2G) to 1.2MHz (AP3602AKTR-G1). Higher switching frequencies reduce inductor and capacitor sizes but may increase EMI considerations. Lower frequencies reduce switching losses but require larger passive components.

Q: Can NCV3065DR2G provide both analog and PWM dimming like MIC2282YMM?

A: The NCV3065DR2G supports both analog and PWM dimming. The MIC2282YMM does not specify dimming capability in the provided parameters. The NCV3065DR2G offers additional dimming flexibility for applications requiring brightness control.

Q: Are all substitute parts suitable for industrial temperature range applications?

A: Three substitutes (LT3478EFE#PBF, NCV3065DR2G, TPS61046YFFR) operate to 125°C (TJ), supporting industrial temperature requirements. The MIC2282YMM and AP3602AKTR-G1 are limited to 85°C (TA), suitable for commercial temperature range applications.
