LTC3723-1/LTC3723-2  
Synchronous Push-Pull  
PWM Controllers  
U
DESCRIPTIO  
FEATURES  
TheLTC®3723-1/LTC3723-2synchronouspush-pullPWM  
controllers provide all of the control and protection func-  
tions necessary for compact and highly efficient, isolated  
power converters. High integration minimizes external  
component count, while preserving design flexibility.  
■
High Efficiency Synchronous Push-Pull PWM  
■
1.5A Sink, 1A Source Output Drivers  
■
Supports Push-Pull, Full-Bridge, Half-Bridge, and  
Forward Topologies  
■
Adjustable Push-Pull Dead-Time and Synchronous  
Timing  
The robust push-pull output stages switch at half the  
oscillator frequency. Dead-time is independently pro-  
grammed with an external resistor. Synchronous rectifier  
timing is adjustable to optimize efficiency. A UVLO pro-  
gram input provides precise system turn-on and turn off  
voltages. The LTC3723-1 features peak current mode  
controlwithprogrammableslopecompensationandlead-  
ing edge blanking, while the LTC3723-2 employs voltage  
mode control with voltage feedforward capability.  
■
Adjustable System Undervoltage Lockout and  
Hysteresis  
■
Adjustable Leading Edge Blanking  
■
Low Start-Up and Quiescent Currents  
■
Current Mode (LTC3723-1) or Voltage Mode  
(LTC3723-2) Operation  
■
Single Resistor Slope Compensation  
■
VCC UVLO and 25mA Shunt Regulator  
■
Programmable Fixed Frequency Operation to 1MHz  
■
50mA Synchronous Output Drivers  
The LTC3723-1/LTC3723-2 feature extremely low operat-  
ing and start-up currents. Both devices provide reliable  
short-circuit and overtemperature protection. The  
LTC3723-1/LTC3723-2 are offered in a 16-pin SSOP  
package.  
■
Soft-Start, Cycle-by-Cycle Current Limiting and  
Hiccup Mode Short-Circuit Protection  
■
5V, 15mA Low Dropout Regulator  
■
Available in 16-Pin SSOP Package
