Intersil's Endura ISL6226 combo power controller combines a synchronous buck pulse width modulation (PWM) controller and a linear low drop out (LDO) regulator in a single 24-lead SSOP IC package. A wide operating voltage range of 5 to 24 V makes this advanced dual controller ideal for powering microprocessor chip sets, memory, audio and graphics ICs.
Component count and costs of the solution design are reduced because no current sense resistor is needed, no discrete Schottky diode is needed parallel to the lower MOSFET and there is only one 5 V power pin, which eliminates one bypass capacitor and a resistor. In addition, only a single resistor is needed for current-limit protection.
The ISL6226 features superior dynamic response, thermal shutdown protection, and high efficiency during light load operation. The PWM controller has an output voltage from 0,9 V to 93% of Vin, up to 3 A output current and a high efficiency over a wide load range. It also provides hysteresis to preserve efficiency in light-load conditions and lossless current sensing using the MOSFET's internal RDS(ON) resistance. Switching frequency is 300/600 kHz.
