Triple Channel Synchronous Step- Down Switcher with Integrated FET Advanced Datasheet IDTP9120 Features Description Input Voltage Range: 2.7V to 5.5V IDTP9120 is a fully integrated power management IC Three step-down converters with integrated FETs designed to provide three programmable voltage rails from a Buck1: 2A single 5V or 3.3V input rail with high efficiency and low Buck2: 2A quiescent currents in sleep mode or no-load condition. Buck3: 3A The device offers selectable direct buck enable inputs or Buck 3 to operate in Buck or Switch mode programmable sequencing with power good and power on Factory Programmable Output Voltage: 0.8 - 3.4V reset generation. Automatic PFM/PWM or forced PWM mode To support low power operation, the IDTP9120 supports Switching frequency 2MHz Optional Programmable Sequence Mode both sleep and standby modes. Power Good and/or Power On Reset Output The IDTP9120 is available in a 4mm x 4mm, 24-ld, QFN -40C to +85C operating temperature range package and is guaranteed to operate over the ambient Package: QFN 24-ld 4 x 4mm x 0.8mm (NBG24) temperature range -40C to +85C.

Once a final customer configuration has been defined, a configuration specific -xx ID will be assigned and used for order and marking. ABSOLUTE MAXIMUM RATINGS Stresses above the ratings listed below can cause permanent damage to the IDTP9120. These ratings are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
