Introduction

AI Translation

The LTC3838-2 is a dual-channel, PolyPhase synchronous step-down DC/DC switching regulator controller. Two independent channels drive all N-channel power MOSFETs. The two channels can also be combined into a multiphase single output configuration with external reference. The controlled on-time, valley current mode control architecture allows for not only fast response to transients without a clock delay, but also constant frequency switching at a steady-load condition. Its proprietary load-release transient detection feature (DTR) significantly reduces overshoot at low output voltages. The switching frequency can be programmed from 200kHz to 2MHz with an external resistor, and can be synchronized to an external clock. Very low tON and tOFF times allow for near 0% and near 100% duty cycles, respectively. Voltage tracking soft start-up and multiple safety features are provided.
