Description

MPL

Optimized Performance with MPS Inductor

The MP3439 is a high-efficiency, synchronous, dual-phase boost converter with an output disconnect function.

The MP3439 adopts constant-on-time (COT) control topology to provide fast transient response. The integrated P-channel synchronous MOSFETs improve efficiency and disconnect the output from the input during shutdown. Dual-phase switching with high frequency provides a small-sized power solution for up to 3A of load current (I_LOAD) from a 1-cell lithium battery.

The MP3439 provides a 400kHz I²C interface that can configure the output voltage (V_OUT), current limit, and light-load operation. It also supports frequency spread spectrum (FSS) to improve EMI performance.

The MP3439 is available in a small-size WLCSP-20 (1.75mmx2.10mm) package.
