The ISL8013A is a high efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 3A continuous output current from a 2. 8V to 5. 5V input supply. It uses a current control architecture to deliver very low duty cycle operation at high frequency with fast transient response and excellent loop stability. The ISL8013A integrates a pair of low ON-resistance P-Channel and N-Channel internal MOSFETs to maximize efficiency and minimize external component count. The 100% duty-cycle operation allows less than 300mV dropout voltage at 3A output current. High 1MHz pulse-width modulation (PWM) switching frequency allows for the use of small external components and the SYNC input enables multiple ICs to synchronize out-of-phase to reduce ripple and eliminate beat frequencies. The ISL8013A can be configured for discontinuous or forced continuous operation at light load. Forced continuous operation reduces noise and RF interference while discontinuous mode provides high efficiency by reducing switching losses at light loads. Fault protection is provided by internal hiccup mode current limiting during short circuit and overcurrent conditions, an output overvoltage comparator and over-temperature monitor circuit. A power-good output voltage monitor indicates when the output is in regulation. The ISL8013A is offered in a space saving 4mmx4mm, Pb-free QFN package with exposed pad leadframes for low thermal resistance. The ISL8013A includes a pair of low ON-resistance P-Channel and N-Channel internal MOSFETs to maximize efficiency and minimize external component count. The 100% duty-cycle operation allows less than 300mV dropout voltage at 3A. The ISL8013A offers a 1ms Power-Good (PG) timer at power-up. When shut down, ISL8013A discharges the output capacitor. Other features include internal soft-start, internal compensation, overcurrent protection, and thermal shutdown. The ISL8013A is offered in a 4mmx4mm 16 Ld QFN package with 1mm maximum height. The complete converter occupies less than 0. 4in2 area.
