反激变换器是电池 CCD 应用程序

资料介绍
摘要: 本文介绍了反激式电源转换器的设计,以操作 CCD 数码相机从四个 AAA 细胞等设备。MAX752 和多个输出变压器送 + 15V,-7.5V 和 5V。第一孔型设计低输入电压下, 了低效率和大电压峰值在 Lx 针。低电压与二极管被改善 MOSFET 运作。由于对非理想变压器行动反激刺受控制的缓冲网络。效率曲线显示大于 50 欧姆负载和 5.25V 输入为 80%。MAX752 操作 170 khz。输入的电压范围为 3.5V 到 6.5V。

APPLICATION NOTE 665
Flyback Converter Serves Battery-Powered CCD Applications

Abstract: This article describes the design of a flyback power converter to operate CCD equipment such as
digital cameras from four AAA cells. The MAX752 and a multiple output transformer deliver +15V, -7.5V and
5V. First pass design had low efficiency at low input voltages, and large voltage spikes on the Lx pin. MOSFET
operation is improved at low voltage with diodes. Flyback spikes due to non-ideal transformer action are
controlled with a snubber network. Efficiency curve shows greater than 80% with a 50-ohm load and 5.25V
input. The MAX752 oper……
