STEVAL-ISA131V2 Datasheet, PDF (1/5 Pages) STMicroelectronics – Ultra-fast load and line transient

STEVAL-ISA131V2
2.8 V - 500 mA, 6 MHz synchronous step-down converter based
on ST1S15J28R
Data brief
Description
STEVAL-ISA131V2 is an 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. This converter working at 6 MHz
switching frequency and is specifically designed
for applications where high efficiency and small
application area are the key factors.
Features
• 85% typical efficiency
• 500 mA output current capability
• 45 μA typical quiescent current
• PFM or PWM operation for best efficiency
over whole load range
• Ultra-fast load and line transient
• Short-circuit and thermal protection
• Tiny external components
• Auto or forced PWM selection with
dedicated pin
• ST1S15J28R in Flip Chip 6 bumps Package
• RoHS compliant
