The MAX651CSA+ from Analog Devices is a BiCMOS step-down DC-DC switching controller. It utilizes a current-limited pulse-frequency-modulated (PFM) control scheme to achieve high efficiency across a broad range of load currents, from 10mA to over 2.5A. This controller offers a preset output voltage of 3.3V, with the capability to be adjusted from 1.5V to the input voltage using external resistors.
Key electrical specifications include a maximum input voltage of 16.5V, a dropout voltage of less than 1V, and a maximum quiescent supply current of 100µA. The device operates at a high switching frequency of up to 300kHz, allowing for the use of miniature surface-mount inductors. It is designed to drive external P-channel MOSFETs for loads greater than 10W.
This controller is suitable for applications requiring high-efficiency step-down regulation, minimum component count, and battery-powered devices. The MAX651CSA+ is available in an 8-SOIC surface-mount package, facilitating compact PCB designs.
