稳压电荷泵提供 50ma 参考电平

资料介绍
图1的替代品在地方的外部电感器和二极管通常与开关稳压器IC1的电压三倍器的DC-DC转换电路。反相和同相驱动器中的MOSFET驱动芯片(IC2)的激活一个二极管/电容网络( D1 -D3的C1- C3 )的三倍。基于单极性司机电荷泵相比, IC2的缓冲/逆变器的结合,使该电路提供更符合当前更少的部件。

APPLICATION NOTE 35
Regulated Charge Pump Delivers 50mA
The DC-DC converter circuit of Figure 1 substitutes a voltage tripler in place of the external inductor and diode normally
associated with switching regulator IC1. Inverting and noninverting drivers in the MOSFET-driver chip (IC2) activate a diode/
capacitor tripling network (D1-D3, C1-C3). In comparison with charge pumps based on single-polarity drivers, the buffer/
inverter combination of IC2 enables this circuit to deliver more current with fewer parts.




The diode-capacitor tripler network in this step-up switching regulator develops 10V f
