MAX1627ESA Description

Short technical summary and product information.

The MAX1627ESA is a high-efficiency, step-down DC-DC controller designed for a wide input voltage range of 2.6V to 16.5V. It supports adjustable output voltages from 1.3V to 16V and can deliver load currents from 1mA to over 2A. This controller utilizes a unique current-limited pulse-frequency-modulation (PFM) control scheme, enabling up to 100% duty cycle operation for very low dropout voltage.

 

Key features include a low quiescent current of 90µA and a shutdown current of 1µA, making it suitable for battery-powered applications. The 300kHz PWM switching frequency helps reduce the size of external components like inductors. The device operates reliably in adverse environments with an operating temperature range of -40°C to +85°C.

 

Packaged in an 8-SOIC surface-mount package, the MAX1627ESA is designed for applications such as green PC power supplies, handheld computers, PDAs, and low-cost notebook computer supplies. Its design minimizes external components and total cost while offering high efficiency, exceeding 90% from 3mA to 2A loads.
