The MP3439 is a high-efficiency, synchronous, dual-phase boost converter with output disconnect.
Constant-on-time (COT) control provides fast transient response. The integrated, synchronous P-channel MOSFETs improve efficiency. These MOSFETs also disconnect the output from the input during shutdown.
High-frequency, dual-phase switching provides a small-sized power solution for up to 3A of load current from a 1-cell Lithium-ion battery.
The MP3439 features a 400kHz I2C interface that can configure the output voltage (VOUT), current limit, and light-load work mode. It also features frequency spread spectrum (FSS) for reduced EMI.
The MP3439 is available in a small WLCSP-20 (1.75mmx2.1mm) package.
