STEVAL-ISA047V2 数据手册 ( 数据表 ) - STMicroelectronics

Description
This demonstration board is based on the ST1S03A, an adjustable current mode PWM step-down DC-DC converter with internal 1.5 A power switch, packaged in a 6-lead DFN 3x3 mm.

FEATUREs
■ Step-down current mode PWM (1.5 MHz) DC-DC converter
■ 2% DC output voltage tolerance
■ Internal soft-start for start-up current limitation and power on delay of 50-100 µs
■ Typical efficiency: > 85%
■ Inhibit function
■ 1.5 A output current capability
■ Not switching quiescent current: max 1.5 mA (overtemperature range)
■ Switch VDS: max 200 mV @ ISW = 750 mA
■ Uses tiny capacitors and inductors
■ RoHS compliant
