The LM5032 dual current mode PWM controller contains all the features needed to control either two independent forward dc/dc converters or a single high current converter comprised of two interleaved power stages. The two controller channels operate 180° out of phase thereby reducing input ripple current. The LM5032 includes a startup regulator that operates over a wide input range up to 100 V and compound (bipolar + CMOS) gate drivers that provide a robust 2.5-A peak sink current. The adjustable maximum PWM duty cycle reduce stress on the primary side MOSFET switches. Additional features include programmable line undervoltage lockout, cycle-by-cycle current limit, hiccup mode fault operation with adjustable response time, PWM slope compensation, soft-start, and a 2-MHz capable oscillator with synchronization capability.

TIDA-00200 — 面向电池充电应用的 120V AC 输入·200W 交错反激式
TIDA-00200 为需要 ~200W 输出功率级别和超精简物料清单的电池充电器应用提供了一种交错反激式拓扑。除了实际的电子元件外,冷却方面的工作也占了总体设计成本的大部分。该设计利用 LM5032 高压双路交错式电流模式控制器,在满载条件下实现了 90% 的出色效率,同时还能有效散热,减少了冷却方面的工作量。通常不需要风扇。使用更小尺寸的散热器可提高设计灵活性。
