G2822SRC1U
800kHz, 3A Synchronous Step-Down Regulator
The G2822S is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 50μA and drops to <1μA in shutdown. The 2.7V to 6.5V input voltage range makes the G2822S ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery run time in portable systems. Switching frequency is internally set at 800kHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increase efficiency and eliminates the need for an external Schottky diode. Built-in soft start function eliminates in-rush current that could damage the system. Output latch-off operation protects the step-down regulator from damage under short circuit and overvoltage conditions.
