Description

The LTC®1530 is a high power synchronous switching regulator controller optimized for 5V to 1.3V-3.5V output applications. Its synchronous switching architecture drives two external N-channel MOSFET devices to provide high efficiency. The LTC1530 contains a precision trimmed  reference and feedback system that provides worst-case output voltage regulation of ±2% over temperature, load current and line voltage shifts. Current limit circuitry senses the output current through the on-resistance of the topside N-channel MOSFET, providing an adjustable current limit without requiring an external low value sense resistor.

The LTC1530 includes a fixed frequency PWM oscillator that free runs at 300kHz, providing greater than 90% efficiency in converter designs from 1A to 20A of output  current. Shutdown mode drops the LTC1530 supply current to 45A.

The LTC1530 is specified for commercial and industrial temperature ranges and is available in the S0-8 package.
