MAX1771CSA+ Description

Short technical summary and product information.

The MAX1771CSA+ is a step-up DC-DC switching controller designed for battery-powered applications requiring high efficiency and low supply current. It provides up to 90% efficiency over a 30mA to 2A load range and can deliver up to 24W of output power.

 

This controller utilizes a unique current-limited pulse-frequency-modulation (PFM) control scheme, offering the benefits of PWM converters with significantly lower quiescent current (110µA max). It supports input voltages from 2V to 16.5V and features a high switching frequency of up to 300kHz, allowing for the use of miniature surface-mount magnetics.

 

The output voltage is preset at 12V but can be adjusted using external resistors. The MAX1771CSA+ optimizes efficiency at low input voltages and reduces noise with a 100mV current-limit threshold. It drives an external N-channel MOSFET switch.

 

Packaged in an 8-SOIC surface-mount package, the MAX1771CSA+ is suitable for applications such as positive LCD-bias generators, flash memory programmers, and portable communicators.
