摘要

提出了一种可驱动H桥功率电路的电荷泵.为了简化电路设计和确保电路稳定性，本电荷泵采用两倍压电荷泵电路拓扑结构，通过加入两路反馈控制电路来提高电荷泵充电电流和输出电压值的控制精度以及电源转换效率.设计采用0.35μm BCD工艺，通过Cadence Spectre仿真器表明，在负载电流为5 mA条件下，电荷泵正常工作时输出电压范围广（10~40 V），电源转换效率最高达到91%，输出电压建立所需时间为579μs.样片实测结果显示，在不同输入电压条件下，输出电压纹波控制在385 m V以下.

Abstract

A charge pump for H-Bridge power driver circuit was proposed in this paper.In order to simplify the circuit complexity and ensure stability

the proposed charge pump is based on voltage doubling charge pump circuit topology

by adding two feedback control loop to precisely control the output voltage and the charging current of the charge pump.Used 0.35 μm BCD process model

the cadence spectre emulator show that charge pump is working properly on 5 mA load current condition.The output voltage range is wide (from 10 V to 40 V)

the highest power efficiency reached 91%

settling time of the output voltage is 579 μs.And the test results show that the ripple of output voltage is below 385 mV.
