BL8526
BL8526 is 2A 1.4M 5.5V Synchronous Buck Converter manufactured by SHANGHAI BELLING.
DESCRIPTION
FEATURES
The BL8526 is a high efficiency synchronous buck regulator. The device operates from an input voltage range of 3.6V to 5.5V and provides an output voltage from 0.8 to 5V while delivering up to 2A of output current.
The internal synchronous switches increase efficiency and eliminate the need for an external Schottky diode. The switching frequency is set by an external resistor or can be synchronized to an external clock. While switching frequency is set to 1.4MHz, BL8526 can allow the use of small external ponents, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples.
100% duty cycle provides low dropout operation extending battery life in portable systems.
