DESCRIPTION
The ST730A is a 5V output CMOS, step-down switching regulator. The ST730A accepts inputs between 5.2V and 11V and delivers 450mA. Typical efficiencies are 85 to 96.
Quiescent supply current is 0.8mA and only 0.3μA in shutdown mode. The output does not exhibit frequency over this specified range. Pulse-width modulation (PWM) current-mode control provides precise output regulation and excellent transient responses. Output voltage accuracy is guaranteed to be ±5 over line, load, and temperature varations.
■ UP TO 450mA LOAD CURRENTS
■ 200kHz HIGH-FREQUENCY CURRENT-MODE PWM
■ 85 TO 96 EFFICIENCIES
■ 33μH OR 100μH PRE-SELECTED INDUCTOR VALUE, NO COMPONENT DESIGN REQUIRED
■ 0.8mA QUIESCENT CURRENT
■ 0.3μA SHUTDOWN SUPPLY CURRENT
■ ADJUSTABLE OUTPUT VOLTAGE
■ OVERCURRENT, SOFT-START AND UNDERVOLTAGE LOCKOUT PROTECTION
■ CYCLE-BY-CYCLE CURRENT LIMITING
■ PACKAGE AVAILABLE: DIP-8 AND SO-8
