Advanced Regulating Pulse Width Modulators  
FEATURES  
DESCRIPTION  
Dual Uncommitted 40V, 200mA  
Output Transistors  
This entire series of PWM modulators each provide a complete pulse width  
modulation system in a single monolithic integrated circuit. These devices in-  
±
clude a 5V reference accurate to 1%, two independent amplifiers usable for  
1% Accurate 5V Reference  
Dual Error Amplifiers  
both voltage and current sensing, an externally synchronizable oscillator  
with its linear ramp generator, and two uncommitted transistor output  
switches. These two outputs may be operated either in parallel for single-  
ended operation or alternating for push-pull applications with an externally  
controlled dead-band. These units are internally protected against double-  
pulsing of a single output or from extraneous output signals when the input  
supply voltage is below minimum.  
Wide Range, Variable Deadtime  
Single-ended or Push-pull  
Operation  
Under-voltage Lockout With  
Hysteresis  
The UC495A contains an on-chip 39V zener diode for high-voltage applica-  
tions where VCC would be greater than 40V, and a buffered output steering  
control that overrides the internal control of the pulse steering flip-flop.  
Double Pulse Protection  
Master or Slave Oscillator  
Operation  
The UC494A is packaged in a 16-pin DIP, while the UC495A is packaged in  
an 18 pin DIP. The UC494A, UC495A are specified for operation over the full  
military temperature range of -55°C to +125°C, while the UC494AC,  
UC495AC are designed for industrial applications from 0°C to +70°C.
