AMS4106 is a medium output current synchronous buck converter. The high side device is integrated into the device. The AMS4106 provides an adaptive gate drive for the external FET. For low current operation this can be replaced with a Schottky diode allowing asynchronous operation. The part has either a fixed internal present PWM frequency of 250 kHz, or externally adjustable up to 600 kHz, allowing smaller inductors where efficiency is less critical and faster transient response is needed. The part uses current mode control for simple compensation and ease of use with low ESR capacitors. It uses a programmable soft start to reduce inrush current and allow large output capacitors to be used where very low ripple is required. The part has enable pin with virtual zero power in shutdown mode. A power good is provided with open collector to facilitate power ready functions. The part is available in SOIC 16 thermally enhanced packages。
