Overview
The MP3394ES-LF-Z is a four-channel boost WLED controller from Monolithic Power Systems, designed for LCD panel backlighting. It operates with an input voltage range of 5V to 28V and delivers up to 200mA per channel. The device utilizes a fixed-frequency current control architecture with a nominal switching frequency of 540kHz. It features a 16-pin SOIC package and supports PWM or DC dimming. Key protections include LED open/short circuit detection, adjustable overvoltage protection, UVLO, and thermal shutdown.
Feature Summary
- Four independent high-precision current sources ensure accurate LED string matching
- Supports cascading multiple units under a single power supply for scalable designs
- Enables flexible brightness control via external PWM or DC input signals
Applications
- Large LCD panel backlight systems
- White LED array drivers
- Portable electronic display modules
Procurement Notes
Verify the specific suffix 'ES' against the manufacturer's latest documentation to confirm package type and temperature grade. Confirm RoHS compliance status as required by your assembly process. Check for end-of-life notifications, as this component may be restricted for new designs in certain regions.
Selection Notes
Select this model when designing systems requiring four distinct LED channels driven from a single boost converter topology. Ensure the external MOSFET and inductor ratings accommodate the 28V maximum output requirement. Verify that the application environment stays within the specified operating temperature range for reliable performance.
Part Context
This component belongs to the MP3394 family of WLED controllers. Variants such as MP3394EF and MP3394SGS offer similar electrical characteristics but differ in package styles like TSSOP or industrial temperature grades. The ES suffix specifically denotes the commercial-grade SOIC-16 packaging configuration.
Replacement Considerations
MP3394EF-LF-Z and MP3394SGS-P are functionally related variants within the same series. Verify pin compatibility and package dimensions before substitution.
