Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP3336GC-P are classified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Topology: Step-Up (Boost) DC-DC regulator
• Number of Outputs: 2 channels
• Dimming Control: I2C and/or PWM capability
• Supply Voltage Range: Minimum 2.5V to 5.5V overlap
• Internal Switch: Integrated
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant

Substitution Groups:

Group 1 – Camera Flash Applications (I2C Dimming, Higher Current): LM3560TLE-20/NOPB is the primary substitute for camera flash designs. This part maintains I2C dimming control and 1A flash current capability, operating within the 2.5V–5.5V supply range. The 16-DSBGA package differs from the main part but provides equivalent electrical functionality for flash applications.

Group 2 – Backlight Applications (I2C Dimming, Lower Current): LM3528TMX/NOPB serves as a substitute for backlight-focused designs. This part provides I2C dimming with 20mA output current per channel and operates across 2.5V–5.5V supply range in a 12-DSBGA package.

Group 3 – PWM Dimming Alternatives (Backlight Applications): TPS61140DRCT, TPS61140DRCR, and TPS61150ADRCT are functionally equivalent substitutes for applications requiring PWM dimming control. These parts operate across 2.5V–6V supply range with 35mA (TPS61140 series) and 34mA (TPS61150A) output current per channel in 10-VSON packages. All three maintain boost topology with dual outputs and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Camera Flash Applications: LM3560TLE-20/NOPB is the designated substitute when camera flash functionality is required. This part maintains I2C dimming control and 1A flash current capability. The operating temperature range is -40°C to 85°C (TA), which is lower than the MP3336GC-P. All parts are ROHS3 compliant and active products.

For Backlight Applications with I2C Control: LM3528TMX/NOPB provides I2C dimming functionality for backlight designs. Output current is limited to 20mA per channel, suitable for lower-power backlight applications. This part is ROHS3 compliant with unlimited MSL rating.

For Backlight Applications with PWM Control: TPS61140DRCT, TPS61140DRCR, and TPS61150ADRCT are functionally equivalent alternatives for PWM-based dimming. TPS61140DRCT and TPS61140DSCR are identical in electrical specification (35mA per channel), differing only in packaging designation. TPS61150ADRCT provides 34mA per channel output. All three operate across 2.5V–6V supply range and are ROHS3 compliant. MSL rating is 2 (1 Year) for all three parts.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and active product status. MSL ratings differ: MP3336GC-P and LM3528TMX/NOPB carry MSL 1 (Unlimited), while TPS61140 and TPS61150A series carry MSL 2 (1 Year). REACH status is unaffected for all parts. ECCN classification is EAR99 across all parts.

Frequently Asked Questions (FAQ)

Q: Can LM3560TLE-20/NOPB replace MP3336GC-P in all applications?

A: LM3560TLE-20/NOPB is functionally equivalent for camera flash applications. Both parts provide I2C dimming control and dual-output boost topology. However, the LM3560TLE-20/NOPB output current is 1A (Flash), compared to 2A for the MP3336GC-P. Operating temperature range differs: LM3560TLE-20/NOPB operates to 85°C (TA) versus 125°C (TJ) for MP3336GC-P. Package type differs: 16-DSBGA versus 20-WLCSP.

Q: What is the difference between TPS61140DRCT and TPS61140DRCR?

A: TPS61140DRCT and TPS61140DRCR are electrically identical. Both provide 35mA output current per channel, PWM dimming control, and 10-VSON (3x3) package. The designations reflect different packaging or tape reel configurations from Texas Instruments. Selection between these two is based on supply chain availability and packaging requirements.

Q: Can PWM-dimming parts (TPS61140, TPS61150A) replace I2C-dimming parts (LM3560, LM3528)?

A: No. PWM and I2C are distinct dimming control interfaces. TPS61140DRCT, TPS61140DRCR, and TPS61150ADRCT use PWM dimming, while LM3560TLE-20/NOPB and LM3528TMX/NOPB use I2C dimming. Application firmware and control circuitry must support the specific dimming protocol. Direct substitution requires redesign of the dimming control interface.

Q: What is the impact of MSL rating differences?

A: MP3336GC-P and LM3528TMX/NOPB carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. TPS61140 and TPS61150A series carry MSL 2 (1 Year), requiring storage in controlled humidity environments and limiting shelf life to one year from manufacturing date. MSL 2 parts require more stringent handling and storage protocols.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—LM3560TLE-20/NOPB, LM3528TMX/NOPB, TPS61140DRCT, TPS61140DRCR, and TPS61150ADRCT—are ROHS3 compliant. REACH status is unaffected for all parts. ECCN classification is EAR99 for all parts.

Q: What package considerations apply when substituting?

A: MP3336GC-P uses 20-WLCSP (1.65x2.05) package. LM3560TLE-20/NOPB uses 16-DSBGA (2.5x2.12). LM3528TMX/NOPB uses 12-DSBGA. TPS61140 and TPS61150A series use 10-VSON (3x3). Package differences require PCB layout redesign, including footprint, via placement, and thermal management modifications. Mechanical compatibility cannot be assumed.

Q: Which substitute part has the highest output current capability?

A: MP3336GC-P provides 2A per channel. LM3560TLE-20/NOPB provides 1A (Flash). LM3528TMX/NOPB provides 20mA. TPS61140DRCT and TPS61140DRCR provide 35mA. TPS61150ADRCT provides 34mA. For high-current applications, LM3560TLE-20/NOPB is the closest substitute, though still limited to 1A compared to the original 2A specification.
