Description

The SX2106 is a synchronous step -down DC/DC

converter that provides wide 4.5V to 21V input

voltage range and 2A continuous load current capability.

The SX2106 fault protection includes cycle -by-cycle

current limit, UVLO, output overvoltage protection and thermal shutdown. The adjustable soft-start

function prevents inrush current at turn-on. This device uses current mode control scheme which

provides fast transient response. Internal

Compensation function reduces external

compensation components and simplifies the design process. In shutdown mode, the supply current is

less than 1μA.

The SX2106 is available in a SOT-23-6 package,

provides good thermal conductance.
