The MIC4680-3.3BM chip is part of the DC DC switching regulators and is a versatile power management chip. It is an adjustable switching buck regulator which provides constant output voltage and supports high current levels. The output current of the chip is adjustable with the external resistor selection. The chip is based on a high-efficiency Pulse width Modulation (PWM) control circuit architecture and is suitable for applications such as notebook computers, PDAs, wireless communications, etc.

The MIC4680-3.3BM chip provides constant output voltage using a voltage feed forward control scheme that senses the output voltage and adjusts the current control loop accordingly. The chip operates over a wide range of input voltages and is capable of delivering up to 3.3A current with a fixed voltage of 3.3V. The current output can be further adjusted by selecting the external resistor value.

The MIC4680-3.3BM chip comes with a power good monitor which monitors the output voltage and informs the system of any changes that may occur in the v
