Overview
The MP4057AGS-Z is a single-stage, single-chip LED lighting driver IC designed for smart LED applications. It supports Buck-Boost and Flyback topologies with a single output channel. The device operates within an input voltage range of 4 V to 27 V and features a fixed switching frequency of 60 kHz. It is housed in an MSOP-10 package and supports PWM dimming. The maximum power dissipation is 830 mW, with a maximum supply current of 500 uA. The operating temperature range spans from -40°C to +125°C.
Feature Summary
- Integrates single-stage conversion for simplified smart LED system design
- Supports both Buck-Boost and Flyback circuit topologies
- Enables precise control via Pulse Width Modulation (PWM) dimming
Applications
- Smart LED lighting systems
- General LED illumination drivers
- Single-channel LED backlighting
Procurement Notes
Verify the specific suffix 'Z' against official Monolithic Power Systems documentation to confirm RoHS compliance status and lead time requirements. Ensure the MSOP-10 package variant matches the required PCB footprint. Cross-reference the datasheet revision history for any updates to electrical characteristics or thermal limits before finalizing the bill of materials.
Selection Notes
Select this component when a compact, single-chip solution for Buck-Boost or Flyback LED driving is required. It is suitable for designs needing operation across a wide 4 V to 27 V input range. Consider the 60 kHz fixed frequency and MSOP-10 package constraints regarding thermal management and board space compared to other MPS LED driver families.
Part Context
The MP4057AGS-Z belongs to the MP4057 series from Monolithic Power Systems, categorized under LED Lighting Drivers. It shares core functionalities with variants like the MP4057AGK-Z but differs in package configuration. This series targets efficient, low-component-count solutions for modern smart lighting architectures requiring integrated power conversion and control.
Replacement Considerations
The MP4057AGK-Z is a documented alternative within the same series, offering identical electrical specifications but utilizing an MSOP-10 package variant. Verify pinout compatibility and thermal performance differences between the specific package options before substitution.
