Abstract: With its small size and large load (10W) capability, the MAX13256 H-bridge transformer driver is an attractive solution forcharging supercapacitors (supercaps). However, a large capacitance on the output of the circuit can force the driver into fault modeat startup, due to the high initial charge current. This application note presents a solution that allows users to charge a largecapacitance without going into fault.

单开关(或称单晶体管)正激转换器是一种最基本类型的基于变压器的隔离降压转换器，广泛用于需要大降压比的应用。这种转换器的优点包括只需单颗接地参考晶体管，及非脉冲输出电流减小输出电容的均方根纹波电流含量等。但这种转换器的功率能力小于半桥或全桥拓扑结构，且变压器需要磁芯复位，使这种转换器的最大占空比限制在约50%。此外，金属氧化物半导体场效应管(MOSFET)开关的漏电压变化达输入电压的两倍或更多，使这种拓扑结构较难于用在较高输入电压的应用。

高的工作电压高达100V N双N沟道MOSFET同步驱动 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSFET. When in regulation, power is derived from the output for higher effi ciency.
