DA9122 - High-Performance Dual-Channel DC-DC Converter

Datasheet Summary

Description

DA9122 is a power management unit (PMU) suitable for supplying CPUs, GPUs, DDR memory rails in single in-line pin package (SIPP) modules, smartphones, tablets, and other handheld applications.

DA9122 integrates two single-phase buck converters, each phase requiring a small external 0.10 µH inductor.

Features

2.5 V to 5.5 V input voltage.
0.3 V to 1.9 V output voltage.
4 MHz nominal switching frequency.
±1 % accuracy (static).
±5 % accuracy (dynamic).
I2C-compatible interface (FM+).
Programmable GPIOs.
Programmable soft-start.
Voltage, current, and temperature supervision.
-40 °C to +85 ºC ambient temperature range.
Package: 24WLCSP 2.48 mm x 1.68 mm (0.4 mm pitch).

DA9122 High-Performance Dual-Channel DC-DC Converter General Description DA9122 is a power management unit (PMU) suitable for supplying CPUs, GPUs, DDR memory rails in single in-line pin package (SIPP) modules, smartphones, tablets, and other handheld applications. DA9122 integrates two single-phase buck converters, each phase requiring a small external 0.10 µH inductor. Each buck is capable of delivering up to 5 A output current at a 0.3 V to 1.9 V output voltage range. The 2.5 V to 5.5 V input voltage range is suitable for a wide variety of low-voltage systems, including, but not limited to, all Li-Ion battery supplied applications. With remote sensing, the DA9122 guarantees the highest accuracy and supports multiple PCB routing scenarios without loss of performance.
