Triple Channel Synchronous Step-

Down Switcher with Integrated FET

Advanced Datasheet

IDTP9120

Features

. Input Voltage Range: 2.7V to 5.5V

Description

IDTP9120 is a fully integrated power management IC

. Three step-down converters with integrated FETs

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.

Buck1: 2A

Buck2: 2A

Buck3: 3A

The device offers selectable direct buck enable inputs or

programmable sequencing with power good and power on

reset generation.

. Buck 3 to operate in Buck or Switch mode

. Factory Programmable Output Voltage: 0.8 - 3.4V

. Automatic PFM/PWM or forced PWM mode

. Switching frequency 2MHz

. Optional Programmable Sequence Mode

. Power Good and/or Power On Reset Output

. -40°C to +85°C operating temperature range

. Package: QFN 24-ld 4 x 4mm x 0.8mm (NBG24)

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.

Applications

Point of Load Regulation in a variety of low power

applications:

. Solid State Disk Drive (SSD) Power Management

. Low Power USB powered applications

. Set Top Box / TV Power Supply

. Portable Gaming
