16V升压IC

GENERAL DESCRIPTION

The SL1576 is a constant frequency, 6-pin

SOT23 current mode step-up converter intended for

small, low power applications. The SL1576

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 SL1576 features automatic shifting to pulse

frequency modulation mode at light loads. The

SL1576 includes under-voltage lockout, current

limiting, and thermal overload protection to prevent

damage in the event of an output overload. The

SL1576 is available in a small 6-pin SOT-23

package.
