Overview
Product Folder Sample & Buy Technical Documents Tools & Software Support & Community Reference Design LM5032 SNVS344B – MARCH 2005 – REVISED DECEMBER 2014 LM5032 High-Voltage Dual Interleaved Current Mode Controller 1 Features •1 Two Independent PWM Current Mode Controllers • Integrated High-Voltage Startup Regulator • Compound 2.
5-A Main Output Gate Drivers • Single Resistor Oscillator Setting to 2 MHz • Synchronizable Oscillator • Programmable Maximum Duty Cycle • Maximum Duty Cycle Fold-Back at High-Line Voltage • Adjustable Timer for Hiccup Mode Current Limiting • Integrated Slope Compensation • Adjustable Line Undervoltage Lockout • Independently Adjustable Soft-Start (Each Regulator) • Direct Interface with Opto-Coupler Transistor • Thermal Shutdown • TSSOP 16-Pin Package 2 Applications • Telecommunication Power Converters • Industrial Power Converters • 42-V Automotive Systems 3 Description 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-bycycle current limit, hiccup mode fault operation with adjustable response time, PWM slope compensation, soft-start, and a 2-MHz capable oscillator with synchronization capability.
