Dual-Channel, N+M≤4 Phases, DC/DC Buck Converter with I2C and Fault Telemetry
PQ6341
With up to 2MHz switching frequency supported, the PQ6341 device is designed to meet power management requirements of ultra-compact applications. With individual loop regulation and protections, the device contains two step-down DC/DC converter channels, with phase configuration programmable between 1+0, 2+0, 3+0, 4+0, 1+1, 2+1, 3+1 and 2+2 options. The device supports an I2C-compatible serial interface for fault telemetry and user customized configuration.
