JW5520S
The JW5520S is a synchronous high-efficiency, boost converter with true output disconnection. The device adopts constant-off-time (COT) control topology.
The device can start up from an input voltage as low as 1.2V. The input switch peak current can be programmable up to 9A and the output average load current limit can be programmable by external resistors.
The typical operation frequency of JW5520S is 600kHz, which allows smaller inductor and capacitors to achieve a small solution size.
During light load condition, PFM is engaged to maintain the maximum efficiency.
JW5520S guarantees robustness with output short circuit protection and thermal shutdown
