描述
1 W# ^! Z) e" e; W4 ?The SLB628 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The SLB628 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.
- |# D, t4 h+ x# h) tThe SLB628 features automatic shifting to pulse frequency modulation mode at light loads. The SLB628 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The SLB628 is available in a small 6-pin SOT-23 package.$ H8 k* z2 X0 q6 C7 F3 F
