G2257Q51U In Stock GMT 4+1 Channels PMIC Authorized GMT Electronic Components Agent

General Description:
The G2257Q51U is designed to provide a comprehensive power solution for mobile phones or data cards. It includes four DC/DC converters and one Low Dropout (LDO) regulator to supply power to each key module of the system, optimized for maximum battery life with low ground current during standby mode operation. All channel DC/DC converters operate at 1.5MHz to optimize size, cost, and efficiency. All synchronous converters are enabled by separate EN-pin control and operate in pulse skipping mode under light load conditions. The G2257Q51U is available in a QFN4X4-24 package.

Features:
– Operates with an input voltage range of 2.7V to 5.5V.
– Features 95% efficient DC/DC converters.
– Independent enable control for each converter.
– Built-in 4-channel synchronous buck converters and 1-channel LDO.
– Bucks can be set to operate with lower static current under low load conditions.
– 180-degree phase shift architecture.
– Fixed 1.5MHz switching frequency for all channels.
– Built-in short circuit protection (SCP), under-voltage protection (UVP), and current limiting on a per-cycle basis for DC/DC converters.
– Integrated thermal shutdown feature.
– VCC with built-in overvoltage protection (OVP) functionality.
– Packaged in a QFN4X4-24 package.

Applications:
The G2257Q51U is suitable for use in a variety of applications within the 3C digital domain, particularly where efficient power management and compact design are required, such as in smartphones and data cards.

This PMIC is recognized for its high efficiency and ability to manage power distribution in complex electronic devices, making it a valuable component in modern power-sensitive technologies.
