Product detail
Product description:

The UCC28C44DR is a high-performance current-mode PWM controller with lower power consumption for improved efficiency and faster current sensing and oscillator frequency. The device is packaged in SOIC-8 and is specified to operate from –40°C to 125°C. The device provides the necessary functions to control a fixed-frequency, peak-current-mode power supply. Reduced startup and operating currents minimize startup losses and low operating power consumption for improved efficiency. The device also features a fast 35ns current-sense output delay time for excellent overload protection on the power switch and ±1-A peak output current capability with the improved rise and fall times to drive large external MOSFETs directly.


Features:

• Operating frequency: 1 MHz Maximum

• 50-μA Startup Current, 100-μA Maximum

• Low operating current: 2.3 mA (at fOSC = 52 kHz)

• Fast, cycle-by-cycle overcurrent limiting: 35-ns

• Peak driving current: ±1-A. 

• Rail-to-rail output:

– 25-ns rise time

– 20-ns fall time

• ±1% accurate 2.5-V error amplifier reference

• Trimmed oscillator discharge current

• Undervoltage lockout protections

• VSSOP-8 package minimizes board space

Applications:

• Switch-mode power supplies

• General purpose single-ended DC-DC or off-line isolated power converters

• Board mount power modules
