capacitor and resistor

General Description  
The LM3477/A is a high-side N-channel MOSFET switching  
regulator controller. It can be used in topologies requiring a  
high side MOSFET such as buck, inverting (buck-boost) and  
zeta regulators. The LM3477/A’s internal push pull driver  
allows compatibility with a wide range of MOSFETs. This, the  
wide input voltage range, use of discrete power components  
and adjustable current limit allows the LM3477/A to be opti-  
mized for a wide variety of applications.  
Applications  
n Local Voltage Regulation  
n Distributed Power  
The LM3477/A uses a high switching frequency of 500kHz to  
reduce the overall solution size. Current-mode control re-  
quires only a single resistor and capacitor for frequency  
compensation. The current mode architecture also yields  
superior line and load regulation and cycle-by-cycle current  
limiting. A 5µA shutdown state can be used for power sav-  
ings and for power supply sequencing. Other features in-  
clude internal soft-start and output over voltage protection.  
The internal soft-start reduces inrush current. Over voltage  
protection is a safety feature to ensure that the output volt-  
age stays within regulation.

) 36% of  
The LM3477A is similar to the LM3477. The primary differ-  
ence between the two is the point at which the device  
transitions into hysteretic mode. The hysteretic threshold of  
the LM3477A is one-third of the LM3477.
