Overview
The MP3364GR-Z is a four-channel boost LED driver IC designed for white LED backlighting in LCD panels. It supports an input voltage range of 3.5 V to 36 V and delivers up to 150 mA per channel. The device features a switching frequency configurable from 400 kHz to 2.2 MHz and operates within a temperature range of -40°C to +125°C. Output voltage spans 600 mV to 36 V, housed in a 24-QFN package.
Feature Summary
- Four independent current sources for driving white LED arrays
- Supports analog and PWM dimming methods
- Includes open LED protection and thermal shutdown
Applications
- Backlighting for small- or medium-sized LCD panels
- Virtual reality display modules
- General LED lighting applications
Procurement Notes
Verify the specific suffix 'Z' against official Monolithic Power Systems documentation to confirm compliance with environmental standards such as RoHS3. Ensure that the QFN-24 package dimensions and pinout match the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring multi-channel LED drive with high dimming ratios. Consider the internal MOSFET characteristics and switching frequency limits relative to external inductor selection. Evaluate thermal performance constraints based on the maximum power dissipation capabilities of the 24-QFN package.
Part Context
This part belongs to the MP3364 series of boost converters from Monolithic Power Systems. It is distinct from single-channel variants like the MP3363GJ-Z and differs from the I2C-controlled MP3364GR-P model. The GR-Z designation specifically identifies the standard PWM/analog dimming version without digital interface control.
Replacement Considerations
Direct substitutes include the MP3364GR-P for designs requiring I2C control instead of analog/PWM inputs. For single-channel applications, the MP3363GJ-Z serves as a functional alternative. Verify pin compatibility and electrical specifications when cross-referencing these options.
