LTC3830/LTC3830-1
High Power Step-Down
Synchronous DC/DC Controllers
for Low Voltage Operation U FEATURES DESCRIPTIO ■ The LTC®3830/LTC3830-1 are high power, high efficiency switching regulator controllers optimized for
3.3V-5V to 1.xV-3.xV step-down applications. A precision internal reference and feedback system provide
±1% output regulation over temperature, load current
and line voltage variations. The LTC3830/LTC3830-1 use
a synchronous switching architecture with N-channel
MOSFETs. Additionally, the chip senses output current
through the drain-source resistance of the upper
N-channel FET, providing an adjustable current limit
without a current sense resistor. ■
