The LTC

3832/LTC3832-1 are high power, high effi-

ciency switching regulator controllers optimized for

3.3V-5V to 0.6V-3.xV step-down applications. A preci-

sion internal reference and feedback system provide

±1%

output regulation over temperature, load current

and line voltage variations. The LTC3832/LTC3832-1 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 MOSFET, providing an adjustable current limit

without a current sense resistor.

The LTC3832/LTC3832-1 operate with an input supply

voltage as low as 3V and with a maximum duty cycle of

>91% over temperature. They include a fixed frequency

PWM oscillator for low output ripple operation. The 300kHz

free-running clock frequency can be externally adjusted or

synchronized with an external signal from 100kHz to 500kHz.

In shutdown mode, the LTC3832 supply current drops to

<10µA. The LTC3832-1 is the SO-8 version without current

limit, frequency adjustment and shutdown functions.
