Product Overview
LTC®3833 is a synchronous step-down DC/DC switching regulator controller targeted for high power applications. It drives all N-channel power MOSFETs. The controlled on-time valley current mode architecture allows for both fast transient response and constant frequency switching in steady-state operation, independent of VIN, VOUT and load current. Differential output voltage sensing along with a precision internal reference combine to offer ±0.67% output regulation and the ability to correct for up to ±500mV variations in the output terminals due to line losses. The operating frequency can be programmed from 200KHz to 2MHz with an external resistor and can be synchronized to an external clock for noise and EMI sensitive applications. Safety features include output overvoltage protection, programmable current limit with foldback, and a power good output signal. Typical applications are distributed power systems, point-of-load converters, computing systems, datacomm systems.
