Data Sheet
Description
Package
SFA0006A is the current mode PWM control IC with SOP8 a primary-side regulation suitable for the automotive system controllers. By employing the primary-side regulation, the IC realizes low ponent counts and the
REF 1
8 VCC downsizing the power supply circuit. For supporting the low consumption power and the low standby power, the IC has an automatic standby function. The IC
P 2 GND 3
7 FB 6 DRV automatically switches to the PWM mode in normal operation, and to the burst oscillation mode at standby. s The IC achieves power supply systems to be more cost n effective with fewer external ponents. ig Features es
