Description

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.
