A Synchronous Boost Converter with Adjustable Output Voltage

The AW3606 is a Large current, High-efficiency synchronous Boost regulator with adjustable output voltage. The AW3606 uses PWM peak current mode control method, in Continuous Conduction Mode (CCM), operate at 2MHz to reduce external device size, save more PCB area. At light load condition, the chip will enter Burst mode automatically to increase efficiency. The AW3606 adopts input peak current limit value adjustable by 1-wire pulse function for power bank application, to adjust the maximum load ability. The bulk switch circuit is integrated to isolate the input port and output port, prevent current from V OUT  to V IN . AW3606 can adjust the output voltage by applying external resistors to FB pin. Otherwise, FB should be grounded and the V OUT would be set to 5V for default. The AW3606 is available in a tiny DFN 8pin package.
