Datasheet

Description

MPL

Optimized Performance with MPS Inductor

The EVL3439-C-00A is an evaluation board designed to demonstrate the capabilities of the MP3439, a high-efficiency, synchronous, dual-phase boost converter with an output disconnect function.

The MP3439 adopts constant-off-time control topology to provide fast transient response. The integrated synchronous MOSFETs disconnect the output from the input during shutdown. Dual-phasing switching with high frequency enables a small-sized power solution for up to 3A of load current from a 1-cell lithium battery.

The MP3439 features an I²C interface to configure the output voltage (V_OUT), current limit, and light-load operation. The MP3439 is available in a WLCSP-20 package.

It is recommended to read the MP3439 datasheet prior to making any changes to the EVL3439-C-00A.
