Overview
Description
The ST735 is a Bi-CMOS, inverting switch mode DC-DC regulator with internal Power MOSFET's that generates a fixed -5V output voltage from a 4V to 6.2V input voltage; is guaranteed an output current of 200mA for inputs greater than 4.5V. The quiescent current for this device is typically of 0.8mA and, in shutdown mode it is reduced to 10μA.

Features
Converts 4.0V to 6.2V input to -5V output
1W guaranteed output power
75% typical efficiency
0.8mA quiescent current
10µA shutdown mode
160KHz fixed frequency oscillator
Current mode PWM converter
Low noise and jitter
Soft start
Simple application circuit
