STEVAL-ISA131V1 STMicroelectronics

STEVAL-ISA131V1 1.82 V - 500 mA, 6 MHz synchronous step-down converter based on the ST1S15 Data brief Description The STEVAL-ISA131V1 is a product evaluation board designed around the ST1S15, a high efficiency miniaturized step-down converter capable to providing 500 mA of output current from an input voltage from 2.3 V to 5.5 V. This converter works at a 6 MHz switching frequency and is specifically designed for applications where high efficiency and small application area are key factors. STEVAL-ISA131V1 Features 85% typical efficiency 500 mA output current capability 45 A typical quiescent current PFM or PWM operation for best efficiency over entire load range Ultra-fast load and line transient Short-circuit and thermal protection Tiny external components Auto or forced PWM selection with dedicated pin ST1S15J18R in Flip-Chip 6-bumps package RoHS compliant January 2014 DocID025871 Rev 1 1/4 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagram STEVAL-ISA131V1 1 Schematic diagram Figure 1.
