LTC3721-1  
Push-Pull PWM Controller  
U
DESCRIPTIO  
FEATURES  
The LTC®3721-1 push-pull PWM controller provides all of  
the control and protection functions necessary for com-  
pact and highly efficient, isolated power converters. High  
integration minimizes external component count, while  
preserving design flexibility.  
■
High Efficiency Push-Pull PWM  
■
1.5A Sink, 1A Source Output Drivers  
■
Adjustable Push-Pull Dead-Time  
■
Adjustable System Undervoltage Lockout and  
Hysteresis  
■
Adjustable Leading Edge Blanking  
The robust push-pull output stages switch at half the  
oscillator frequency. Dead-time is independently pro-  
grammedwithanexternalresistor. AUVLOprograminput  
providesprecisesystemturn-onandturnoffvoltages.The  
LTC3721-1 features peak current mode control with pro-  
grammable slope compensation and leading edge  
blanking.  
■
Low Start-Up and Quiescent Currents  
■
Current Mode Operation  
■
Single Resistor Slope Compensation  
■
VCC UVLO and 25mA Shunt Regulator  
■
Programmable Fixed Frequency Operation to 1MHz  
■
Soft-Start, Cycle-by-Cycle Current Limiting and  
Hiccup Mode Short-Circuit Protection  
5V, 15mA Low Dropout Regulator  
■
■
The LTC3721-1 features extremely low operating and  
start-up currents and reliable short-circuit and  
overtemperature protection. The LTC3721-1 is offered in  
16-pin SSOP and (4mm × 4mm) QFN packages.
