CD5032
CD5032 is Dual Interleaved Current Mode Controller manufactured by CYT.
Description
The CD5032 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 prised of two interleaved power stages. The two controller channels operate 180°out of phase thereby reducing input ripple current. The CD5032 operates over a wide input range up to 100 V and pound (bipolar + CMOS) gate drivers that provide a robust 2.5A 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 pensation, soft-start, and a 2MHz capable oscillator with synchronization capability.
