1 / 23 page  FN9110 Rev 9.00 Page 1 of 23 May 20, 2016 FN9110 Rev 9.00 May 20, 2016 ISL6721 Flexible Single-Ended Current Mode PWM Controller DATASHEET The ISL6721 is a low power, single-ended Pulse Width Modulating (PWM) current mode controller designed for a wide range of DC/DC conversion applications including Boost, Flyback and isolated output configurations. Peak current mode control effectively handles power transients and provides inherent overcurrent protection. Other features include a low power mode where the supply current drops to less than 200µA during overvoltage and overcurrent shutdown faults. This advanced BiCMOS design features low operating current, adjustable operating frequency up to 1MHz, adjustable soft-start, and a bidirectional SYNC signal that allows the oscillator to be locked to an external clock for noise sensitive applications. Applications • Telecom and datacom power • Wireless base station power • File server power • Industrial power systems • Isolated buck and Flyback regulators • Boost regulators Features • 1A MOSFET gate driver • 100µA start-up current • Fast transient response with peak current mode control • Adjustable switching frequency up to 1MHz • Bidirectional synchronization • Low power disable mode • Delayed restart from OV and OC shutdown faults • Adjustable slope compensation •Adjustable soft-start • Adjustable overcurrent shutdown threshold • Adjustable UV and OV monitors • Leading edge blanking • Integrated thermal shutdown • 1% tolerance voltage reference • Pb-free available (RoHS compliant) Related Literature • AN1384, “ISL6841EVAL3Z Evaluation Board for General Purpose Industrial Applications” • AN1491, “ISL6721EVAL3Z: Resonant Reset Forward Converters for Low Power” ISL6721 (16 LD TSSOP) (16 LD SOIC) TOP VIEW GATE ISENSE SYNC SLOPE UV OV RTCT VC PGND VCC VREF LGND SS COMP 1 2 3 4 5 6 7 16 15 14 13 12 11 10 8 9 ISET FB |
