STEVAL-ISA131V3 Datasheet, PDF (1/4 Pages) STMicroelectronics – 500 mA output current capability

STEVAL-ISA131V3
1.82 V – 500 mA, 6 MHz synchronous step-down converter
based on the ST1S15
Data brief
Description
The STEVAL-ISA131V3 is a product evaluation
board designed around the ST1S15, a high-
efficiency miniaturized step-down converter able
to provide 500 mA output current from an input
voltage of 2.3 V to 5.5 V.
The converter operates at a switching frequency
of 6 MHz and is specifically designed for
applications where high efficiency and small
application areas are key factors.
Features
• 85% typical efficiency
• 500 mA output current capability
• 45 µA typical quiescent current
• PFM or PWM operation for best efficiency
over the entire load range
• Ultra-fast load and line transients
• Short-circuit and thermal protection
• Tiny external components
• Auto or forced PWM selection using a
dedicated pin
• ST1S15TPUR in DFN6 (2 x 2 mm)
• RoHS compliant
