XRP7664
2A 18V Synchronous Step-Down Converter
March 2013
GENERAL DESCRIPTION
The XRP7664 is a synchronous current-mode PWM step down (buck)
voltage regulator capable of a continuous output current up to 2Amps.
A wide 4.
5V to 18V input
voltage range allows for single supply operations from industry standard 5V and 12V power rails.
With a 340kHz constant operating frequency and integrated high and low side 100mΩ/100mΩ
MOSFETs, the XRP7664 reduces the overall component count and solution footprint.
Current-mode control provides fast transient response and cycle-bycycle current limit.
An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to...
