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.
