SL4007 大功率升压恒压芯片 2.8-24V输入 输出ADJ

General Description
  The SL4007 is boost topology switching regulator for wide operating voltage applications. It
provides built-in gate driver pin for driving external N-MOSFET. The non-inverting input of error
amplifier connects to a 1.2V precision reference voltage. It has programmable switching frequency set
by external resistor, and programmable inductor peak current limit connects a resistor from CS to GND.
Current mode control and external compensation network make is easy and flexible to stabilize the
system.
  The SL4007 is available in the small footprint SOP-8L(EP) package to fit in space-saving PCB
layout for application fields.
