Renesas Electronics Corporation Compact Synchronous Buck Regulators ISL8026AFRTAJZ

Description
The ISL8026, ISL8026A are highly efficient, monolithic, synchronous step-down DC/DC converters that can deliver 6A of continuous output current from a 2.5V to 5.5V input supply. The devices use current mode control architecture to deliver a very low duty cycle operation at high frequency with fast transient response and excellent loop stability. The ISL8026, ISL8026A integrate a very low ON-resistance P-Channel (36mO) high-side FET and N-Channel (13mO) low-side FET to maximize efficiency and minimize external component count. The 100% duty-cycle operation allows less than 180mV dropout voltage at 6A output current. The operation frequency of the Pulse-width Modulator (PWM) is adjustable from 500kHz to 4MHz. The default switching frequency, which is set by connecting the FS pin high, is 1MHz for the ISL8026 and 2MHz for the ISL8026A. The ISL8026, ISL8026A can be configured for discontinuous or forced continuous operation at light load. Forced continuous operation reduces noise and RF interference, while discontinuous mode provides higher efficiency by reducing switching losses at light loads. Fault protection is provided by internal hiccup mode current limiting during short-circuit and overcurrent conditions. Other protection, such as overvoltage and over-temperature, are also integrated into the device. A power-good output voltage monitor indicates when the output is in regulation. The ISL8026, ISL8026A offer a 1ms Power-good (PG) timer at power-up. When in shutdown, the ISL8026, ISL8026A discharge the output capacitor through an internal soft-stop switch. Other features include internal fixed or adjustable soft-start and internal/external compensation. The ISL8026, ISL8026A are offered in a space saving 16 Ld 3x3 Pb-free TQFN package with an exposed pad for improved thermal performance and 0.8mm maximum height. The complete converter occupies less than 0.22 in2 area.
