LM5037  
Dual-Mode PWM Controller With Alternating Outputs  
General Description  
Features  
The LM5037 PWM controller contains all the features neces-  
sary to implement balanced double-ended power converter  
topologies, such as push-pull, half-bridge and full-bridge.  
These double-ended topologies allow for higher efficiencies  
and greater power densities compared to common single-  
ended topologies such as the flyback and forward. The  
LM5037 can be configured for either voltage mode or current  
mode control with minimum external components. Two alter-  
nating gate drive outputs are provided, each capable of 1.2A  
peak output current. The LM5037 can be configured to oper-  
ate directly from the input voltage rail over a wide range of  
13V to 100V. Additional features include programmable max-  
imum duty cycle limit, line under-voltage lockout, cycle-by-  
cycle current limit and a hiccup mode fault protection with  
adjustable timeout delay, soft-start and a 2 MHz capable os-  
cillator with synchronization capability, precision reference  
and thermal shutdown.  
High voltage (100V) start-up regulator  
Alternating outputs for double-ended topologies  
Current-mode or feed-forward voltage-mode control  
Programmable maximum duty cycle lLimit  
2% feedback reference accuracy  
High gain-bandwidth error amplifier  
Programmable line under-voltage lockout (UVLO) with  
adjustable hysteresis  
Versatile dual mode over-current protection with hiccup  
delay timer  
Programmable soft-start  
Precision 5V reference output  
Current sense leading edge blanking  
Resistor programmed 2 MHz capable oscillator  
Oscillator synchronization capability with low frequency  
lockout protection
