TYPICAL APPLICATION

Figure 1. Basic Application Circuit

The SB6284 is a constant frequency, 6-pin SOT23

current mode step-up converter intended for small,

low power applications. The

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 SB6284featuresautomatic shifting to pulse

frequency modulation mode at light loads. The

SB6284includes under -voltage lockout, current

limiting, and thermal overload protection to prevent

damage in the event of an output overload. The

SB6284is available in a small 6-pin SOT-23

package.
