G2280HL1U datasheet pdf 10A Fully Integrated Synchronous Boost Converter

The G2280HL1U is a high efficiency, synchronous, COT, boost converter .The G2280 has wide input voltage range from 2.7V to 12V to support applications with single cell or two cell Lithium batteries. The device has 10A switch current capability and is capable of providing an output voltage up to 12.6V.

The G2280 uses adaptive constant off-time peak current control topology to regulated the output voltage. In moderate to heavy load condition, the G2280 works in the PWM mode. In light load condition, the device has two operation modes selected by the MODE pin.

One is the PFM mode and another one is forced PWM mode. The switching frequency in the PWM mode is adjustable ranging from 200kHz to 2.2MHz by an
external resistor. A programmable soft-start function, and an adjustable switching peak current limit function are also implanted in G2280. In addition, 13.2V output overvoltage protection, cycle-by-cycle overcurrent protection, and thermal shutdown protection are also embedded.

The G2280 is available in QFN3.5×4.5-20 package.
