LM5032  
High Voltage Dual Interleaved Current Mode Controller  
General Description  
Features  
n Two independent PWM current mode controllers  
n Integrated high voltage startup regulator  
n Compound 2.5A main output gate drivers  
n Single resistor oscillator setting to 2 MHz  
n Synchronizable oscillator  
The LM5032 dual current mode PWM controller contains all  
the features needed to control either two independent for-  
ward dc/dc converters or a single high current converter  
comprised of two interleaved power stages. The two control-  
ler 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 100V and  
compound (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  
under-voltage lockout, cycle-by-cycle current limit, hiccup  
mode fault operation with adjustable response time, PWM  
slope compensation, soft-start, and a 2 MHz capable oscil-  
lator with synchronization capability.  
n Programmable maximum duty cycle  
n Maximum duty cycle fold-back at high line voltage  
n Adjustable timer for hiccup mode current limiting  
n Integrated slope compensation  
n Adjustable line under-voltage lockout  
n Independently adjustable soft-start (each regulator)  
n Direct interface with opto-coupler transistor  
n Thermal shutdown  
Applications  
n Telecommunication Power Converters  
n Industrial Power Converters  
n +42V Automotive Systems  
Packages  
n TSSOP-16
