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.

For all available packages, see the orderable addendum at the end of the datasheet.

TIDA-00200 — 適用于電池充電應(yīng)用的 120V 交流 200W、90% 效率、交錯型反激式參考設(shè)計

TIDA-00200 為需要 ~200W 輸出功率級別和超精簡物料清單的電池充電器應(yīng)用提供了一種交錯反激式拓?fù)?。除了實際的電子元件外，冷卻方面的工作也占了總體設(shè)計成本的大部分。該設(shè)計利用 LM5032 高壓雙路交錯式電流模式控制器，在滿載條件下實現(xiàn)了 90% 的出色效率，同時還能有效散熱，減少了冷卻方面的工作量。通常不需要風(fēng)扇。使用更小尺寸的散熱器可提高設(shè)計靈活性。
