LM1577/LM2577 Series  
SIMPLE SWITCHER® Step-Up Voltage Regulator  
General Description  
Features  
n Requires few external components  
n NPN output switches 3.0A, can stand off 65V  
n Wide input voltage range: 3.5V to 40V  
n Current-mode operation for improved transient  
response, line regulation, and current limit  
n 52 kHz internal oscillator  
The LM1577/LM2577 are monolithic integrated circuits that  
provide all of the power and control functions for step-up  
(boost), flyback, and forward converter switching regulators.  
The device is available in three different output voltage ver-  
sions: 12V, 15V, and adjustable.  
Requiring a minimum number of external components, these  
regulators are cost effective, and simple to use. Listed in this  
data sheet are a family of standard inductors and flyback  
transformers designed to work with these switching regula-  
tors.  
n Soft-start function reduces in-rush current during start-up  
n Output switch protected by current limit, under-voltage  
lockout, and thermal shutdown  
Included on the chip is a 3.0A NPN switch and its associated  
protection circuitry, consisting of current and thermal limiting,  
and undervoltage lockout. Other features include a 52 kHz  
fixed-frequency oscillator that requires no external compo-  
nents, a soft start mode to reduce in-rush current during  
start-up, and current mode control for improved rejection of  
input voltage and output load transients.  
Typical Applications  
n Simple boost regulator  
n Flyback and forward regulators  
n Multiple-output regulator
