MP2980
36V, Synchronous Buck-Boost Controller with Digital Interface and Current Monitor
DESCRIPTION
The MP2980 is a synchronous, four-switch, buck-boost controller capable of regulating different output voltages with a wide input voltage (VIN) range and high efficiency. The MP2980 provides a digital interface that supports output voltage (VOUT) configuration, VOUT slewrate control, and constant output current (IOUT) limit configuration. This makes the MP2980 wellsuited for USB power delivery (PD) designs in USB Type-C power supplies.
The MP2980 uses valley current control in buck mode and peak current control in boost mode to provide fast load transient response and smooth buck-boost mode transients.
