MAX770CSA+ Description

Short technical summary and product information.

The MAX770CSA+ is a step-up DC-DC switching controller from Maxim Integrated, providing high efficiency of 90% across a load range of 10mA to 1A. It utilizes a unique current-limited pulse-frequency-modulation (PFM) control scheme, offering the efficiency benefits of PWM converters while consuming minimal supply current (110µA max).

 

This controller supports output power up to 15W and features a high switching frequency of 300kHz, enabling the use of small, surface-mount magnetics. The MAX770/MAX771/MAX772 series accepts input voltages from 2V to 16.5V, with preset output voltages of 5V (MAX770), 12V (MAX771), and 15V (MAX772), or adjustable outputs. The MAX773 variant offers a wider input range and similar output voltage options.

 

Applications for the MAX770CSA+ include battery-powered devices, portable communicators, and positive LCD-bias generators. It drives external N-channel MOSFET switches, making it suitable for various power management needs in compact electronic systems.
