MCHPMIC33153YHJ-TR
Overview
The MIC33153YHJ-TR is a high-efficiency 1.2A synchronous buck regulator module featuring an integrated inductor to simplify PCB layout and reduce electromagnetic interference. It utilizes Microchip's HyperLight Load technology to maintain high efficiency even under light load conditions, making it ideal for battery-powered applications. The device operates at a 4MHz switching frequency, allowing for the use of very small output capacitors while providing ultra-fast transient response.
Why Choose This Part
The integration of the power inductor directly into the 3.0mm x 3.5mm TDFN package eliminates a major source of EMI and simplifies the design cycle. Engineers benefit from a programmable soft-start to manage inrush current and a Power Good (PG) output for easy system sequencing. Its high switching frequency and advanced control loop ensure exceptionally low output ripple and rapid response to load steps.
Applications
Key Specifications
Getting Started
To evaluate this module, design a PCB following the datasheet's recommended layout to ensure proper thermal management of the 14-PowerTFDFN package. Set the output voltage between 0.62V and 3.6V using a standard resistor divider connected to the FB pin. Ensure that low-ESR ceramic capacitors are placed close to the VIN and VOUT pins to maintain stability and minimize noise.
