Product Details
LinkSwitch-LP switcher ICs cost effectively replace all unregulated isolated linear transformer based (50/60 Hz) power supplies up to 3 W output power. For worldwide operation, a single universal input design replaces multiple linear transformer based designs. The self-biased circuit achieves an extremely low no-load consumption of under 150 mW. The internal oscillator frequency is jittered to significantly reduce both quasi- peak and average EMI, minimizing filter cost.
Lowest System Cost and Advanced Safety Features Provide Superior Performance over Linear and RCC
- Lowest component count switcher
- Very tight parameter tolerances using proprietary IC trimming technology and transformer construction techniques enable Clampless™ designs – decreases component count/system cost and increases efficiency
- Hysteretic thermal shutdown protection – eliminates the thermal fuse used with linear transformers or additional components in RCC designs
- Frequency jittering greatly reduces EMI – enables low cost input filter configuration
- Proprietary E-Shield™ transformer eliminates Y capacitor
- Universal input range allows worldwide operation
- Auto-restart reduces delivered power by >85% during short circuit and open loop fault conditions
- Simple ON/OFF control, no loop compensation needed
- High bandwidth provides fast turn on with no overshoot and excellent transient load response
