GENERAL DESCRIPTION
The 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.
