MP3383GF-P

Overview

The MP3383GF-P is a step-up WLED controller from Monolithic Power Systems designed for driving four LED strings in large LCD panel backlighting applications. It operates with an input voltage range of 6 V to 33 V and supports a maximum output voltage of 80 V. The device provides a maximum string current of 400 mA per channel and functions at a switching frequency of 500 kHz. It utilizes a buck topology configuration within the driver architecture and is housed in a TSSOP-16EP package. The component ensures reliable operation across a temperature range of -40°C to +125°C.

Feature Summary

• Supports four independent LED current channels for uniform backlighting control
• Integrates PWM dimming capability for precise brightness adjustment
• Includes short circuit and thermal protection mechanisms for system safety

Applications

• Large LCD panel backlighting systems
• White LED (WLED) array drivers
• High-brightness display modules

Procurement Notes

Verify the specific suffix 'P' against the manufacturer's latest documentation to confirm packaging and material compliance details. Ensure the selected variant matches the required operating temperature range and pinout configuration for your PCB layout. Cross-reference the datasheet revision date to guarantee compatibility with current design standards and regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when designing high-power backlight solutions requiring four distinct LED channels. It is suitable for applications needing a wide input voltage range up to 33 V and high output voltage capabilities up to 80 V. Consider the TSSOP-16EP package constraints and the 500 kHz switching frequency for thermal management and EMI filtering requirements during the initial schematic design phase.
