Product Description
- Description
- LinkSwitch-HFintegrates a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high voltage switched current source, frequency jittering, cycle-by-cycle current limit, and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry.
- The 200 kHz maximum switching frequency allows very low flux transformer designs, practically eliminating audible noise with the simple ON/OFF control scheme using standard
- varnished transformer construction. Efficient operation at this high switching frequency is achieved due to the optimized switching characteristics and small capacitances of the integrated power MOSFET.
- Product Highlights
- Features Optimized for Lowest System Cost
- • Fully integrated auto-restart for short-circuit and open loop protection
- • Self-biased supply – saves transformer auxiliary winding and associated bias supply components
- • Tight tolerances and negligible temperature variation on key parameters eases design and lowers cost
- • High maximum switching frequency allows very low flux density transformer designs, practically eliminating audible noise
- • Frequency jittering greatly reduces EMI
- • Packages with large creepage to high voltage pin
- • Lowest component count switcher solution
- Much Better Performance over Linear/RCC
- • Lower system cost than RCC, discrete PWM and other integrated solutions
- • Universal input range allows worldwide operation
- • Simple ON/OFF control – no loop compensation needed
- • No bias winding – simpler, lower cost transformer
- • High frequency switching – smaller and lower cost transformer
- • Very low component count – higher reliability and single side printed circuit board
- • High bandwidth provides fast turn on with no overshoot and excellent transient load response
- • Current limit operation rejects line frequency ripple
- • Built-in current limit and hysteretic thermal shutdown protection
- Applications
- • Chargers for cell/cordless phones, PDAs, digital cameras, MP3/portable audio devices, shavers etc.
- • Standby and auxiliary supplies
