Product Overview

The LT3667EMSE#TRPBF is a 40V 400mA Step-Down Switching Regulator with dual fault protected LDOs. The buck regulator includes a high efficiency switch, a boost diode, the necessary oscillator, control and logic circuitry. Current mode topology is used for fast transient response and good loop stability. Low ripple burst mode operation maintains high efficiency at low output currents while keeping output ripple below 15mV in a typical application. Each LDO supplies 200mA of output current with a typical dropout voltage of 340mV and each LDO have an accurate resistor programmable current limit. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection.
  • Triple output supply from a single input requires only one inductor
  • Adjustable 250kHz to 2.2MHz switching frequency
  • Synchronizable between 300kHz and 2.2MHz
  • Programmable undervoltage lockout
  • Power good indicators
