Global Mixed-mode Technology G2249 7+3 Channels PMIC Features General Description 3.0V ~ 5.5V Input Voltage Operation The G2249 provide a complete power supply solution 95% Efficient DC/DC Converter for handsets or data card. It contains 7 dc/dc Built-in 7-ch synchronous buck converter, 3-ch converters and 3 LDOs to power each critical blocks of LDOs mobile phone, and is optimized for maximum battery Bucks and LDOs can be set to lower IQ at low life, featuring a low ground current when in standby load mode operation. All channels DC/DC converters Buck2, Buck3, Buck5 and Buck6 Supports DVS operate at one fixed frequency of 3.0MHz or 1.5MHz Function to optimize size, cost, and efficiency. All Synchronous Built-In Power ON/OFF Sequence for PMU converters operate at pulse skipping mode at light load. Built-In Short Circuit Protection (SCP), Under 2 The G2249 features a I C compatible interface. Voltage Protection (UVP), and cycle-by cycle current limit for DC/DC Converters LDOs are Programmable to Voltage Options by The G2249 is available in TQFN5X5-40 package. 2 I C Built-In Thermal Shutdown Function Built-In VCC OVP Function Applications TQFN5X5-40 Package Mobile Handsets TV Dongle Smart Phone Set Top Box Ordering Information ORDER TEMP.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2. Device are ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF capacitor discharged through a 1.5K resistor into each pin.
