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.
