LM3488/LM3488Q  
High Efficiency Low-Side N-Channel Controller for  
Switching Regulators  
General Description  
Key Specifications  
The LM3488 is a versatile Low-Side N-FET high performance  
controller for switching regulators. It is suitable for use in  
topologies requiring low side FET, such as boost, flyback,  
SEPIC, etc. Moreover, the LM3488 can be operated at ex-  
tremely high switching frequency in order to reduce the overall  
solution size. The switching frequency of LM3488 can be ad-  
justed to any value between 100kHz and 1MHz by using a  
single external resistor or by synchronizing it to an external  
clock. Current mode control provides superior bandwidth and  
transient response, besides cycle-by-cycle current limiting.  
Output current can be programmed with a single external re-  
sistor.  
Wide supply voltage range of 2.97V to 40V  
100kHz to 1MHz Adjustable and Synchronizable clock  
frequency  
±1.5% (over temperature) internal reference  
5µA shutdown current (over temperature)  
Features  
LM3488Q is AEC-Q100 qualified and manufactured on an  
Automotive Grade Flow  
8-lead Mini-SO8 (MSOP-8) package  
Internal push-pull driver with 1A peak current capability  
The LM3488 has built in features such as thermal shutdown,  
short-circuit protection and over voltage protection. Power  
saving shutdown mode reduces the total supply current to  
5µA and allows power supply sequencing. Internal soft-start  
limits the inrush current at start-up.
