LT3724IFE#PBF

LINEAR TECHNOLOGY  LT3724IFE#PBF  直流/直流控制器, 电流模式, 4V至60V, 1路输出, 升压, 降压, 反相, SEPIC, 225kHz, TSSOP-16

The is a DC/DC Controller offers a wide 4 to 60V input range 7.5V minimum startup voltage and can implement step-down, step-up, inverting and SEPIC topologies. The LT3724 includes burst mode operation, which reduces quiescent current below 100µA and maintains high efficiency at light loads. An internal high voltage bias regulator allows for simple biasing and can be back driven to increase efficiency. Additional features include fixed frequency current-mode control for fast line and load transient response, a gate driver capable of driving large N-channel MOSFETs, a precision under voltage lockout function, 10µA shutdown current, short-circuit protection and a programmable soft-start function that directly controls output voltage slew rates at startup which limits inrush current, minimizes overshoot and facilitates supply sequencing.
