LM2727/LM2737  
N-Channel FET Synchronous Buck Regulator Controller  
for Low Output Voltages  
General Description  
Features  
n Input power from 2.2V to 16V  
The LM2727 and LM2737 are high-speed, synchronous,  
switching regulator controllers. They are intended to control  
currents of 0.7A to 20A with up to 95% conversion efficien-  
cies. The LM2727 employs output over-voltage and under-  
voltage latch-off. For applications where latch-off is not de-  
sired, the LM2737 can be used. Power up and down  
sequencing is achieved with the power-good flag, adjustable  
soft-start and output enable features. The LM2737 and  
LM2737 operate from a low-current 5V bias and can convert  
from a 2.2V to 16V power rail. Both parts utilize a fixed-  
frequency, voltage-mode, PWM control architecture and the  
switching frequency is adjustable from 50kHz to 2MHz by  
adjusting the value of an external resistor. Current limit is  
achieved by monitoring the voltage drop across the on-  
resistance of the low-side MOSFET, which enhances low  
duty-cycle operation. The wide range of operating frequen-  
cies gives the power supply designer the flexibility to fine-  
tune component size, cost, noise and efficiency. The adap-  
tive, non-overlapping MOSFET gate-drivers and high-side  
bootstrap structure helps to further maximize efficiency. The  
high-side power FET drain voltage can be from 2.2V to 16V  
and the output voltage is adjustable down to 0.6V.  
n Output voltage adjustable down to 0.6V  
n Power Good flag, adjustable soft-start and output enable  
for easy power sequencing  
n Output over-voltage and under-voltage latch-off  
(LM2727)  
n Output over-voltage and under-voltage flag (LM2737)  
n Reference Accuracy: 1.5% (0˚C - 125˚C)  
n Current limit without sense resistor  
n Soft start  
n Switching frequency from 50 kHz to 2 MHz  
n TSSOP-14 package
