Regulating Pulse Width Modulators  
FEATURES  
DESCRIPTION  
• 8 to 35V Operation  
The UC1525B/1527B series of pulse width modulator integrated circuits  
are designed to offer improved performance and lowered external parts  
count when used in designing all types of switching power supplies. The  
on-chip +5.1V buried zener reference is trimmed to ±0.75% and the input  
common-mode range of the error amplifier includes the reference voltage,  
eliminating external resistors. A sync input to the oscillator allows multiple  
units to be slaved or a single unit to be synchronized to an external system  
clock. A single resistor between the CT and the discharge terminals provide  
a wide range of dead time adjustment. These devices also feature built-in  
soft-start circuitry with only an external timing capacitor required. A shut-  
down terminal controls both the soft-start circuitry and the output stages,  
providing instantaneous turn off through the PWM latch with pulsed shut-  
down, as well as soft-start recycle with longer shutdown commands. These  
functions are also controlled by an undervoltage lockout which keeps the  
outputs off and the soft-start capacitor discharged for sub-normal input volt-  
ages. This lockout circuitry includes approximately 500mV of hysteresis for  
jitter-free operation. Another feature of these PWM circuits is a latch follow-  
ing the comparator. Once a PWM pulse has been terminated for any rea-  
son, the outputs will remain off for the duration of the period. The latch is  
reset with each clock pulse. The output stages are totem-pole designs ca-  
pable of sourcing or sinking in excess of 200mA. The UC1525B output  
stage features NOR logic, giving a LOW output for an OFF state. The  
UC1527B utilizes OR logic which results in a HIGH output level when OFF.
