IR3508ZMTRPBF Product Details

The IR3508Z Phase IC combined with any IR XPhase3TM Control IC provides a full featured and flexible way to implement a power solution for the latest high performance CPUs and ASICs. The “Control” IC provides overall system control and interfaces with any number of “Phase” ICs which each drive and monitor a single phase of a multiphase converter. The XPhase3TM architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches.
The IR3508Z disables its current sense amplifiers when entering power savings mode. The recommended use for these Phase ICs is for applications without adaptive voltage positioning where two or more power stages will be operating in power savings mode.
• Power State Indicator (PSI) interface provides the capability to maximize the efficiency at light loads.
• Anti-bias circuitry
• 7V/2A gate drivers (4A GATEL sink current)
• Support converter output voltage up to 5.1 V (Limited to VCCL-1.4V)
• Loss-less inductor current sensing
• Phase delay DFF bypassed during PSI assertion mode to improve output ripple performance
• Over-current protection during PSI assertion mode operation
• Feed-forward voltage mode control
• Integrated boot-strap synchronous PFET
• Only four external components per phase
• 3 wire analog bus connects Control and Phase ICs (VID, Error Amp, IOUT)
• 3 wire digital bus for accurate daisy-chain phase timing control without external components
• Debugging function isolates phase IC from the converter
• Self-calibration of PWM ramp, current sense amplifier, and current share amplifier
• Single-wire bidirectional average current sharing
• Small thermally enhanced 20L 4 X 4mm MLPQ package
• RoHS compliant

    Excellent! Отлично. Посылка шла 1 месяц до СПб. Купил 6v 150ma для ремонта лампочек JAZZWAY 15Вт на драйвере MT7606. Подошли отлично, лампа снова работает. Ранее в ламах стояли диоды на 9v 100ма. Надеюсь, что эти диоды проработают дольше, т. к. тока 150ма с запасом хватает ;-) Спасибо продавцу и рекомендую к покупке.
