L6917B 5 BIT PROGRAMMABLE DUAL-PHASE CONTROLLER 2 PHASE OPERATION WITH SYNCRHONOUS RECTIFIER CONTROL ULTRA FAST LOAD TRANSIENT RESPONSE INTEGRATED HIGH CURRENT GATE DRIVERS: UP TO 2A GATE CURRENT SO-28 TTL-COMPATIBLE 5 BIT PROGRAMMABLE ORDERING NUMBERS:L6917BD OUTPUT COMPLIANT WITH VRM 9.0 L6917BDTR (Tape & Reel) 0.8% INTERNAL REFERENCE ACCURACY 10% ACTIVE CURRENT SHARING ACCURACY DESCRIPTION DIGITAL 2048 STEP SOFT-START The device is a power supply controller specifically OVERVOLTAGE PROTECTION designed to provide a high performance DC/DC con- OVERCURRENT PROTECTION REALIZED version for high current microprocessors. USING THE LOWER MOSFET S R OR A dsON The device implements a dual-phase step-down con- SENSE RESISTOR troller with a 180 phase-shift between each phase. 300 kHz INTERNAL OSCILLATOR A precise 5-bit digital to analog converter (DAC) al- OSCILLATOR EXTERNALLY ADJUSTABLE lows adjusting the output voltage from 1.100V to UP TO 600kHz 1.850V with 25mV binary steps. POWER GOOD OUTPUT AND INHIBIT The high precision internal reference assures the se- FUNCTION lected output voltage to be within 0.8%. The high REMOTE SENSE BUFFER peak current gate drive affords to have fast switching PACKAGE: SO-28 to the external power mos providing low switching losses. APPLICATIONS The device assures a fast protection against load POWER SUPPLY FOR SERVERS AND over current and load over/under voltage. An internal WORKSTATIONS crowbar is provided turning on the low side mosfet if POWER SUPPLY FOR HIGH CURRENT an over-voltage is detected. In case of over-current, MICROPROCESSORS the system works in Constant Current mode.
