LNK6769V, AC/DC Converter IC, LinkSwitch-HP Family, Flyback, 85 VAC - 265 VAC, 39 W, eDIP-11
Semiconductors - ICs\Power Management ICs - PMIC\AC / DC Off Line Converters
LinkSwitch™-HP device monolithically integrates a controller and high voltage power MOSFET into one package. It has a newly developed analogue control scheme which enables continuous conduction mode, primary side regulated power supplies up to 90W without efficiency limitation of DCM or audible noise. It uses an enhanced peak current mode PWM control scheme with multi-mode operation. The multi-mode control engine uses error amplifier output signal voltage at COMPENSATION pin to set operating peak current and switching frequency to maintain output voltage in regulation. For COMPENSATION pin voltages lower than VC(MCM) (typ 1.25V), device enters multi-cycle modulation (MCM) with a fixed peak current of 25% of programmed current limit. Several innovative improvements have been added to peak current mode control to allow primary side regulated CCM operation with no instability. It is used in LCD monitor, TV, adapter, appliances, embedded power supply (DVD, set-top box) and industrial.
• EcoSmart™ energy efficient, high power off-line switcher with accurate primary side regulation (PSR)
• 650V MOSFET for lowest system cost
• High design flexibility for low system cost, dramatically simplifies power supply designs
• Extensive protection features, frequency jittering reduces EMI filter cost
• Extended creepage to DRAIN pin, heat sink is connected to SOURCE for low EMI
• Auto-restart limits power delivery to 3% during overload faults
• Output overvoltage protection (OVP), auto-restart or latching, line brown-in/out protection
• 132KHz operation reduces transformer and power supply size, accurate programmable current limit
• Accurate thermal shutdown (OTP), hysteretic or latching
• 75% efficiency with 1W input at 230VAC, 50% efficiency with 0.1W input at 230VAC
