TS19375

PWM Step-Up Controller

1/8

Version: B11

SOP-8

General Description

The TS19375 is high efficient PWM step-up controller. Designed to drive an external N-channel MOSFET, Output

voltage is programmable with 1.0V of standard voltage supply internal, and using externally connected

components, output voltage (FB) can be set up at will.

The TS19375 can be operated at switching frequencies of 500kHz allowing for easy filtering and low noise, the

size of the external components can be reduced. An enable function and thermal shutdown functions are built

inside. The soft-start time can be programmed by outside capacitor; the function prevents overshoot at startup.
