IDT P9120-00NBGI & P9122 multi-channel power management ICs are designed to provide 2 (P9122) or 3 (P9120) factory programmable voltage rails from a single 3.3V or 5V input rail with high efficiency and low quiescent current 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. To support low power operation the P9120-00NBGI supports both sleep and standby modes, and the P9122 supports a configurable sleep mode. Both are available in a 4mm x 4mm, 24 pin QFN package and guaranteed to operate over the ambient temperature range.
