The LTC3873ETS8-5#TRPBF is a constant frequency current mode DC/DC controller designed for boost, flyback, and SEPIC converter topologies. It operates at a fixed 200kHz switching frequency and provides a ±1.5% accurate voltage reference.
The controller features a low quiescent current of 300μA during normal operation and only 50μA during micropower start-up, making it suitable for power-sensitive applications. The undervoltage lockout thresholds are set at 4.1V (rising) and 2.9V (falling).
The device is housed in a TSOT-23-8 surface mount package and operates from -40°C to 85°C for the E-grade version.

Estimated market price range - modelled values for guidance only, not live distributor offers.
The switching frequency is constant at 200kHz.
The VCC supply voltage should be between 4.1V (undervoltage lockout rising threshold) and 9V (absolute maximum).
The quiescent current is typically 300μA during normal operation and 50μA during micropower start-up.
The part is available in a TSOT-23-8 surface mount package.
The LTC3873E-5 version operates from -40°C to 85°C.
The voltage reference accuracy is ±1.5%.
