MP3336GC-Z LED Driver IC Equivalent & Substitute Parts

Part Overview

The MP3336GC-Z is an active LED driver IC manufactured by Monolithic Power Systems Inc., designed for camera flash applications. This dual-output DC-DC boost regulator operates with I2C and PWM dimming control, delivering 2A per channel in a compact 20-WLCSP package. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified for applications requiring equivalent LED driver functionality with boost topology, dual outputs, and surface mount packaging. Substitutes may differ in current capacity, voltage specifications, dimming protocol, and thermal operating range based on specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP3336GC-Z are qualified based on the following core parameters:

• Dual-output DC-DC boost regulator topology with internal switching capability
• Surface mount packaging (WLCSP, DSBGA, VSON, or DFN variants)
• Supply voltage range overlap with 2.7V minimum and 5.5V maximum
• PWM dimming capability (I2C dimming is specific to MP3336GC-Z and not required for substitution)
• Active product status with ROHS3 compliance

The substitute parts listed below meet these criteria with variations in current capacity, output voltage, switching frequency, and thermal operating range. Selection depends on specific application current and voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, meeting baseline regulatory requirements for electronic component selection.

The MP3336GC-Z operates at higher current capacity (2A per channel) compared to substitute options. LM3630ATME and TPS61140DRCR/TPS61140DRCT are rated for significantly lower current outputs (28.5mA and 35mA respectively), suitable for lower-power LED applications. LT3466EDD#PBF provides intermediate current capacity (400mA) with extended supply voltage range to 24V.

Operating temperature range differs between the main part and substitutes. MP3336GC-Z maintains junction temperature operation to 125°C, while all substitutes operate to 85°C ambient temperature maximum. This distinction is critical for thermal-constrained applications.

Moisture sensitivity levels vary: MP3336GC-Z and LM3630ATME carry MSL 1 (unlimited shelf life), while TPS61140DRCR and TPS61140DRCT carry MSL 2 (1-year shelf life), affecting storage and handling requirements.

Package footprints differ across all parts. MP3336GC-Z uses 20-WLCSP, LM3630ATME uses 12-DSBGA, LT3466EDD#PBF uses 10-DFN, and both TPS61140 variants use 10-VSON. PCB layout and assembly compatibility must be evaluated for each substitution.

Frequently Asked Questions (FAQ)

Q: Can LM3630ATME replace MP3336GC-Z in a camera flash application?

A: LM3630ATME is a dual-output boost regulator with PWM dimming, but current capacity is limited to 28.5mA per channel versus 2A for MP3336GC-Z. Substitution is only viable if application current requirements do not exceed 28.5mA. LM3630ATME lacks I2C dimming control present in MP3336GC-Z.

Q: What are the key differences between TPS61140DRCR and TPS61140DRCT?

A: Both parts are electrically identical with matching specifications: 35mA per channel, 2.5V to 6V supply range, 1.2MHz switching frequency, and 10-VSON packaging. The difference is packaging format: TPS61140DRCR is supplied in Tape & Reel, while TPS61140DRCT is also supplied in Tape & Reel. Both carry MSL 2 rating.

Q: Is LT3466EDD#PBF suitable for high-current LED driver applications?

A: LT3466EDD#PBF provides 400mA per channel, significantly lower than MP3336GC-Z (2A). It is suitable for backlight applications but not for high-current camera flash or similar 2A-class applications. Extended supply voltage range (2.7V to 24V) and higher output voltage (39.5V) make it suitable for different application classes.

Q: How does operating temperature range affect part selection?

A: MP3336GC-Z operates to 125°C junction temperature, providing thermal margin for high-power applications. All substitute parts operate to 85°C ambient maximum. In thermally constrained designs, MP3336GC-Z is preferred. Substitutes are acceptable for room-temperature or controlled-environment applications.

Q: What packaging considerations apply when substituting these parts?

A: MP3336GC-Z uses 20-WLCSP (1.65x2.05mm), the smallest footprint. Substitutes use larger packages: 12-DSBGA (1.64x1.24mm), 10-DFN (3x3mm), or 10-VSON (3x3mm). PCB layout, trace routing, and assembly equipment compatibility must be re-evaluated for each substitution. Smaller packages may offer space advantages but require higher assembly precision.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (LM3630ATME, LT3466EDD#PBF, TPS61140DRCR, TPS61140DRCT) carry ROHS3 compliance status matching MP3336GC-Z.
