LTC1530 High Power Synchronous Switching Regulator Controller FEATURES DESCRIPTIO n High Power Buck Converter from 5V or 3.3V Input The LTC 1530 is a high power synchronous switching n Adjustable Current Limit in S0-8 with regulator controller optimized for 5V to 1.3V-3.5V output Topside FET R Sensing applications. Its synchronous switching architecture drives DS(ON) n No External Sense Resistor Required two external N-channel MOSFET devices to provide high n Hiccup Mode Current Limit Protection efficiency. The LTC1530 contains a precision trimmed n Adjustable, Fixed 1.9V, 2.5V, 2.8V and 3.3V Output reference and feedback system that provides worst-case n All N-Channel MOSFET Synchronous Driver output voltage regulation of 2% over temperature, load n Excellent Output Regulation: 2% over Line, Load current and line voltage shifts. Current limit circuitry and Temperature Variations senses the output current through the on-resistance of n High Efficiency: Over 95% Possible the topside N-channel MOSFET, providing an adjustable n Fast Transient Response current limit without requiring an external low value sense n Fixed 300kHz Frequency Operation resistor. n Internal Soft-Start Circuit The LTC1530 includes a fixed frequency PWM oscillator n Quiescent Current: 1mA 45m A in Shutdown that free runs at 300kHz, providing greater than 90% efficiency in converter designs from 1A to 20A of output U current. Shutdown mode drops the LTC1530 supply cur- APPLICATIO S rent to 45m A. n Power Supply for Pentium II, AMD-K6 -2, SPARC, The LTC1530 is specified for commercial and industrial ALPHA and PA-RISC Microprocessors temperature ranges and is available in the S0-8 package. n High Power 5V to 1.3V-3.5V Regulators , LTC and LT are registered trademarks of Linear Technology Corporation.
