PS7516内置NMOS 80mΩ / PMOS120mΩ
用MOS来代替二极管整流,MOS管功耗更低,升压效率比用的二极管整流,效率相差有的5%以上。
而用二极管做整流的做的的效率也只为90%。
PS7516工作电压2.5V-5.5V,适用于锂电池3.7V-4.2V升压5V1A应用;
更高效的移动电源方案。
PS7516是SOT23-6封装
The device is based on a current-mode control
topology and uses a constant frequency
pulse-width modulator to regulate the output
voltage. The controller limits the current through
the power switch on a pulse by pulse basis. The
current sensing circuit is integrated in the device;
therefore, no additional components are required.
Due to the nature of the boost converter topology
used here, the peak switch current is the same as
the peak inductor current, which will be limited by
the integrated current limiting circuits under normal
operating conditions.
