FEATURES  
DESCRIPTIO  
The LTC®1530 is a high power synchronous switching  
regulator controller optimized for 5V to 1.3V-3.5V output  
applications.Itssynchronousswitchingarchitecturedrives  
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.  
■
High Power Buck Converter from 5V or 3.3V  
Main Power  
■
Adjustable Current Limit in S0-8 with  
Topside FET RDS(ON) Sensing  
■
No External Sense Resistor Required  
■
Hiccup Mode Current Limit Protection  
■
Adjustable, Fixed 1.9V, 2.5V, 2.8V and 3.3V Output  
■
All N-Channel MOSFET Synchronous Driver  
■
Excellent Output Regulation: ±2% over Line, Load  
and Temperature Variations  
■
High Efficiency: Over 95% Possible  
■
Fast Transient Response  
■
Fixed 300kHz Frequency Operation  
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 cur-  
rent to 45µA.  
■
Internal Soft-Start Circuit  
■
Quiescent Current: 1mA, 45µA in Shutdown

APPLICATIO S  
Power Supply for Pentium® II, AMD-K6®-2, SPARC,  
■
The LTC1530 is specified for commercial and industrial  
temperature ranges and is available in the S0-8 package.
