General Description

The GL4010Y4 is a compact, fully integrated and high efficiency Buck-Boost converter for loading

less than 500mA. It can operate at an input voltage range of 2.7 – 5.5V. And its output voltage

can be programmed through I2C from 1.8V to 5.2V.

GL4010Y4 employs a proprietary 4-cycle control scheme to achieve a high efficiency conversion in all

stages of operation, input voltage is higher, lower or close to output voltage, and keep the transition

between each mode smoothly. It also maintains a low 20uA operation current during zero load.

With a standard I2C interface, one can set the output voltage at any level between 1.8V and 5.2V. In

addition, a VSEL pin with high / low digital input is provided for user to switch output voltage much

faster given the voltage setting stored in the register corresponding to VSEL=1 and 0 respectively.

GL4010Y4 is housed in a DFN2x2-10L package, together with a tiny inductor and 2 capacitors, it

provides an extreme compact solution for a programmable power system.
