Regulating Pulse Width Modulator  
FEATURES  
DESCRIPTION  
Reduced Supply Current  
The UC1526A Series are improved-performance pulse-width modu-  
lator circuits intended for direct replacement of equivalent non- “A”  
versions in all applications. Higher frequency operation has been  
enhanced by several significant improvements including: a more ac-  
curate oscillator with less minimum dead time, reduced circuit de-  
lays (particularly in current limiting), and an improved output stage  
with negligible cross-conduction current. Additional improvements  
include the incorporation of a precision, band-gap reference gener-  
ator, reduced overall supply current, and the addition of thermal  
shutdown protection.  
Oscillator Frequency to 600kHz  
Precision Band-Gap Reference  
7 to 35V Operation  
Dual 200mA Source/Sink Outputs  
Minimum Output Cross-Conduction  
Double-Pulse Suppression Logic  
Under-Voltage Lockout  
Along with these improvements, the UC1526A Series retains the  
protective features of under-voltage lockout, soft-start, digital cur-  
rent limiting, double pulse suppression logic, and adjustable  
deadtime. For ease of interfacing, all digital control ports are TTL  
compatible with active low logic.  
Programmable Soft-Start  
Thermal Shutdown  
TTL/CMOS Compatible Logic Ports  
5 Volt Operation (VIN = VC = VREF = 5.0V)  
Five volt (5V) operation is possible for “logic level” applications by  
connecting VIN, VC and VREF to a precision 5V input supply. Consult  
factory for additional information.
