Product Introduction
The UCx84xA series of fixed-frequency pulse-width modulation (PWM) controllers are designed to operate at a switching frequency of 500kHz. These controllers are designed for peak current mode (PCM) and can be used in both isolated and non-isolated power supply designs. These controllers can drive FETs directly from the output, capable of sourcing and sinking up to 1A of gate drive current. These devices also feature a built-in low-impedance amplifier, which can be used in non-isolated designs to control the power supply output voltage and feedback loop.
Features
- Optimized for off-line and DC/DC converters
- Low startup current (< 0.5mA)
- 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
- Operating frequency up to 500kHz
Applications
- Switched-Mode Power Supplies (SMPS)
- DC/DC Converters
- Power Modules
- Industrial PSUs
- Battery-Powered PSUs
