AP6608 DC/DC 升压恒压芯片 高效率 2A 升压转换器IC

The AP6608 is a constant frequency, 6-pin SOT23
current mode step-up converter intended for small,
low power applications. The AP6608 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 AP6608 features automatic shifting to pulse
frequency modulation mode at light loads. The
AP6608 includes under-voltage lockout, current
limiting, and thermal overload protection to prevent
damage in the event of an output overload. The
AP6608 is available in a small 6-pin SOT-23
package.
