The LTM4601 DC/DC μModule regulator is a completehigh power density stepdown regulator for up to 12Acontinuous (14A Peak) loads. The device is housed ina small 15mm ¥ 15mm ¥ 2.8mm LGA surface mountpackage, thus the large power dissipation is a challengein some applications. This thermal application note willprovide guidelines for using the μModule regulator inambient environments with or without air fl ow. Loadcurrent derating curves are provided for several inputvoltages and output voltages versus ambient temperatureand air fl ow.

提出了一种24V/15A 直流变换器的设计方法。主电路采用推挽正激电路，通过在传统推挽电路的基础上增加一个箝位电容，起到抑制偏磁和开关管关断电压尖峰的作用。控制采用峰值电流控制方式（Peak CurrentControlled Model，简称PCCM），为了克服其对占空比要求的限制，加入了斜坡补偿环节。在进行详细的理论分析基础上，给出了主电路和控制电路一些关键参数的设计步骤；最后通过原理样机的研制，验证了理论分析的正确性。

量测/测试所面临之问题 此测试验证上，要使用NI公司之LAB VIEW及DAQ CARD来取代AUDIO PRECISION及其所附软体ATS。首先需克服硬体解析度上的差异，再来是FFT（FAST FOURIER TRANSFORM,快速传立业转换）演算未予的撰写，这将会影响MULTI-TONE讯号上Peak值的侦测。另外，以RS-232为I/O介面，并呼叫客户所提供之DLL档来与DUT内的IC沟通，但因LAB VIEW无法直接呼叫其STRUCTURE，故需用VC++再编译一层新的DLL来供LAB VIEW使用。
