MAX1651ESA Description

Short technical summary and product information.

The MAX1651ESA is a BiCMOS, step-down DC-DC switching controller designed for high efficiency over a wide load range. It utilizes a unique current-limited pulse-frequency-modulated (PFM) control scheme, offering the benefits of PWM converters with significantly lower supply current.

 

Key electrical specifications include an input voltage range of 3V to 16V, a maximum switching frequency of up to 300kHz, and a maximum duty cycle of 96.5%. The device provides a step-down function with a positive output configuration and operates as a buck topology. It features an enable control and is suitable for applications requiring high-efficiency step-down regulation, such as battery-powered devices and 5V-to-3.3V conversions.

 

This controller is housed in an 8-SOIC package and supports surface mount mounting. It is designed to drive external P-channel MOSFETs for loads greater than 12.5W. The operating temperature range is -40°C to 85°C (TA).
