Description

IDTP9120 is a fully integrated 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.

To support low power operation, the IDTP9120 supports

both sleep and standby modes.

The IDTP9120 is available in a 4mm x 4mm, 24-ld, QFN

package and is guaranteed to operate over the ambient

temperature range -40°C to +85°C.
