Step Down Synchronous Switcher 24-Pin QFN T/R

IDTP9122 is a fully integrated power management IC designed to provide 2 factory programmable voltage rails from a single 5V or 3.3V input rail with high efficiency and low quiescent currents in sleep mode or no-load condition. The device offers selectable direct buck enable inputs or a factory programmable sequencing with power good and power on reset generation. To support low power standby operation, the IDTP9122 supports a configurable sleep mode. The IDTP9122 is available in a 4mm x 4mm, 24-ld, QFN package and guaranteed to operate over the ambient temperature range -40°C to +85°C.
