Description
The UCC3915N is a Hot Swap Controller component categorized as an Electronic Component. This current-mode Pulse Width Modulated (PWM) controller contains control and protection functions necessary to have an offline, flyback or forward converter with minimum external components.
Specifications and Features
- Very low start-up supply current - 50 µA typical
- Low operating supply current - 1.2 mA typical
- Accurate, internally-trimmed, fixed frequency oscillator (100 kHz). No external timing components required
- Internal slope compensation - No external ramp components needed
- Built-in over-voltage and under-voltage detection
- High-speed over-current trip - 170 ns typical
- Over-voltage clamp on supply voltage (VDD)
- Internal divider regulates VDD to 12 V - No external divider needed
- Leading edge blanking of the current sense signal
- Control frequency modulated over a narrow band to reduce Electromagnetic Interference (EMI)
- High output drive capability - 150 ns typical rise and fall time into 2 nF load
- Wide bandwidth (10 MHz) error amplifier with external compensation pin and simple interface to optocoupler
- Accurate internal bandgap reference
Application Scenarios
The UCC3915N is suitable for the development of off-line switched mode power supplies, laptop computer mains adaptors, and printer power supplies.
