SDB628
High Efficiency 1.2MHz
2A Step Up Converter
GENERAL DESCRIPTION
The SDB628 is a constant frequency, 6-pin SOT23
current mode step-up converter intended for small,
low power applications. The SDB628 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 SDB628 features automatic shifting to pulse
frequency modulation mode at light loads. The
SDB628 includes under-voltage lockout, current
limiting, and thermal overload protection to prevent
damage in the event of an output overload. The
SDB628 is available in a small 6-pin SOT-23
package.
