SX1308 PDF Datasheet – 1.2MHz, 2A, Step Up Converter

A step-up converter, also known as a boost converter or voltage booster, is a type of DC-DC (Direct Current to Direct Current) power converter circuit or device used to increase the voltage level of a DC power source to a higher level. It is an essential component in various electronic applications where a higher voltage is required than what the input power source can provide.

Part Number: SX1308

Function: High Efficiency 1.2MHz, 2A, Step Up Converter

Package: SOT-23-6 Pin Type

Manufacturer: Suosemi

The SX1308 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The IC switches at 1.2MHz and allows the use of tiny, low cost
capacitors and inductors 2mm or less in height.

Internal soft-start results in small inrush current and extends battery life. The features automatic shifting to pulse frequency modulation mode at light loads. The device includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload.[…]
