The IDT P9120 is a fully integrated multi-purpose power management IC designed to provide three 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 programmable sequencing with power good and power on reset generation. For low power operation, the P9120 supports both sleep and standby modes. The IDTP9120 is available in a 4x4 mm, 24-ld, QFN package and is guaranteed to operate over the ambient temperature range -40°C to +85°C.
