UCC38C44
Description
The UCCx8C4x family are high-performance, current-mode PWM controllers. The UCCx8C4x is an enhanced BiCMOS version with pin-for-pin compatibility to the industry standard UCx84xA family and UCx84x family of PWM controllers.
Key Features
- Enhanced replacement for UCx84x and UCx84xA family with pin-to-pin compatibility
- Operating frequency: 1MHz Maximum
- 50μA Startup Current, 100μA Maximum
- Low operating current: 2.3mA (at fOSC = 52kHz)
- Fast, cycle-by-cycle overcurrent limiting: 35ns
- Peak driving current: ±1A. Rail-to-rail output: - 25ns rise time - 20ns fall time
- ±1% accurate 2.5V error amplifier reference
- Trimmed oscillator discharge current
- Undervoltage lockout protections
- VSSOP-8 package minimizes board space
