Product Introduction
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.
Features
- 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
- Meets industry standard requirements for thermal overload 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
- Meets HV creepage requirements between DRAIN and all other pins, both on the PCB and at the package
- Proprietary E -Shield™ transformer eliminates Y - capacitor
- Hysteretic thermal shutdown protection – automatic recovery improves field reliability
- 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
- Easily meets all global energy efficiency regulations with no added components
- No - load consumption <150 mW at 265 VAC input
- ON/OFF control provides constant efficiency to very light loads – ideal for mandatory CEC regulations
Applications
- Chargers for cell/cordless phones, PDAs, power tools, MP3/portable audio devices, shavers etc.
- Standby and auxiliary supplies
