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.
