RAD-TOLERANT CLASS-V REGULATING PULSE WIDTH MODULATOR

FEATURES

DESCRIPTION

•

QML-V Qualified, SMD 5962-89511

(1)

Rad-Tolerant: 30 kRad (Si) TID

The UC1525B pulse width modulator integrated

circuit is designed to offer improved performance and

lowered external parts count when used in designing

all types of switching power supplies. The on-chip

5.1-V 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

8-V to 35-V Operation

only an external timing capacitor required.

shutdown terminal controls both the soft-start circuitry

and the output stages, providing instantaneous turn

off through the PWM latch with pulsed shutdown, 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 voltages. This lockout circuitry includes

approximately 500 mV of hysteresis for jitter-free

operation. Another feature of these PWM circuits is a

latch following the comparator. Once a PWM pulse

has been terminated for any reason, the outputs

remain off for the duration of the period. The latch is

reset with each clock pulse. The output stages are

totem-pole designs capable of sourcing or sinking in

excess of 200 mA. The UC1525B output stage

features NOR logic, giving a LOW output for an OFF

state.

(1) Radiation tolerance is a typical value based upon initial device

qualification with dose rate = 10 mrad/sec. Radiation Lot
