GENERAL DESCRIPTION

The HX7208 is a constant frequency, 6-pin SOT23

current mode step-up converter intended for small,

low power applications. The HX7208 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 HX7208 features automatic shifting to pulse

frequency modulation mode at light loads. The

HX7208 includes under-voltage lockout, current

limiting, and thermal overload protection to prevent

damage in the event of an output overload. The

HX7208 is available in a small 6-pin SOT-23

package.
