RAD-TOLERANT CLASS V, CURRENT-MODE PWM CONTROLLER
JG PACKAGE
QML-V Qualified, SMD 5962-86704
(TOP VIEW)
Rad-Tolerant: 30 kRad (Si) TID (1)
Optimized for Offline and DC-to-DC Converters
Low Start-Up Current (<0.5 mA)
Trimmed Oscillator Discharge Current
Automatic Feed Forward Compensation
Pulse-by-Pulse Current Limiting
Enhanced Load Response Characteristics
The UC1843A control IC is a pin-for-pin compatible
Undervoltage Lockout With Hysteresis
improved version of the UC1843. Providing the
Double-Pulse Suppression
necessary
features
to
control
current-mode
switched-mode power supplies, this device has the
High-Current Totem-Pole Output
following improved features. Start up current is
Internally Trimmed Bandgap Reference
guaranteed to be less than 0.5 mA. Oscillator
500-kHz Operation
discharge is trimmed to 8.3 mA. During undervoltage
Low R
O Error Amplifier
lockout, the output stage can sink at least 10 mA at
less than 1.2 V for VCC over 5 V.
