TOP233P
Description
TOPSwitch-FX uses the proven TOPSwitch topology and cost effectively integrates many new functions that reduce system cost and, at the same time, improve design flexibility,.
Key Features
- Fully integrated soft-start for minimum stress/overshoot
- Externally settable accurate current limit
- Wider duty cycle for more power, smaller input capacitor
- Line under-voltage (UV) detection: no turn off glitches
- Line overvoltage (OV) shutdown extends line surge limit
- Line feed forward with maximum duty cycle (DCMAX) reduction rejects ripple and limits DCMAX at high line
- Single resistor sets OV/UV thresholds, DCMAX reduction
- Frequency jittering reduces EMI and EMI filtering costs
- Regulates to zero load without dummy loading
- 132 kHz frequency reduces transformer/power supply size
