SLUS224F –SEPTEMBER 1994–REVISED OCTOBER 2017
UCx84xA Current-Mode PWM Controller Features
Optimized for Off-Line and DC-DC Converters Low Start-Up Current(< 0.5 mA) Trimmed Oscillator Discharge Current Automatic Feedforward Compensation Pulse-by-Pulse Current Limiting Enhanced Load Response Characteristics Undervoltage Lockout With Hysteresis Double Pulse Suppression High-Current Totem Pole Output Internally-Trimmed Bandgap Reference Upto 500-kHz Operation Createa Custom Design Using the UCx84xA With
the WEBENCH® Power Designer Applications Switch Mode Power Supplies (SMPS) DC-DC Converters Power Modules Industrial PSU Battery Operated PSU Description
The UCx84xA familyof control devicesisa pin-for-pin
compatible improved versionof the UCx84x family.
Providing the necessary featuresto control current-
modeor switched-mode power supplies, this family
devices has many improved features: startup current less than 0.5 mA, oscillator dischargeis trimmed
8.3 mA, and during UVLO, the output stage can least10 mAat less than 1.2V for VCC over5
