Product Details

PowerBlox Switching Regulators, EXAR

EXAR PowerBlox™ synchronous step-down switching regulators offer high efficiency in compact space-saving packages. They feature a wide input voltage range of 4.5 to 22V, allowing single supply operation from industry standard 5, 12 & 19.6V power rails. A constant on-time (COT) emulated current mode control scheme allows extremely fast line and load transient response using ceramic output capacitors and requires no loop compensation.

Wide input voltage range of 4.5 to 22V
Adjustable Output Voltage
Controller, drivers, bootstrap diode and MOSFETs integrated in one compact package
Proprietary constant on-time control
No loop compensation required and stable operation with ceramic output capacitors
Programmable on-time with constant 200-800 kHz switching frequency
Precision Enable, Power-Good flag and Programmable Soft-start
