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
