Product Overview
The TOP242PN is a TOPSwitch-GX Integrated Off-line Switcher IC flyback supply provides 4 outputs, delivering 7W from a 230VAC ±15% input. Resistor R7 programs the internal TOP242PN current limit to 78% of nominal, just above the level needed for full load at low line. This feature allows a more continuous transformer design for better efficiency and cross-regulation, without requiring a larger core size. Resistor R12, C10 and L2 filter conducted EMI; R12 is a flameproof fusible type, also functioning as a fuse. For lower cost, if the supply does not have to meet conducted EMI with the output connected to earth ground, the common mode choke can be replaced with a π filter. A Zener clamp (D11 and VR1) was selected over an RCD clamp to minimize zero load consumption.
- <0.5W Input power at zero load
- Low component count design occupies 80 x 30 x 16mm
- Integrated soft-start reduces start-up component stresses
- Extended power range for higher power applications
- Eliminate or reduce cost of external components
- Externally programmable accurate current limit
- No turn off glitches line under-voltage (UV) detection
- Line over voltage (OV) shutdown extends line surge limit
- 132kHz Frequency reduces transformer/power supply size
- Hysteretic thermal shutdown for automatic fault recovery
- Large thermal hysteresis prevents PC board overheating
