A4401  
Automotive Quasi-Resonant Flyback Control IC  
Features and Benefits  
Description  
Multiple output regulator  
This device provides all the necessary control functions to  
provide the power rails for driving a vacuum fluorescent  
display(VFD)usingminimalexternalcomponents.Thepower  
supply is based on a quasi-resonant, discontinuous flyback  
converter, operating near the critical conduction boundary. A  
novel adaptive turn-on control scheme is used to optimize the  
turn-on and turn-off phase of the MOSFET, to reduce EMI  
emissions while minimizing switching losses.  
7 to 40 V input supply  
Low EMI conducted and radiated emissions  
Adaptive quasi-resonant turn on/off control  
Minimal number of external components  
Enable input which can be driven with respect to the  
battery voltage  
The converter is self-oscillating, operating at switching  
frequencies depending on the input voltage, load, and external  
components. An onboard linear regulator that is powered  
directly from the battery provides the housekeeping supply,  
avoiding the need for complex bias supplies.  
Internal diagnostics provide comprehensive protection  
against overloads, input undervoltage, and overtemperature  
conditions.  
Package: 8-pin narrow SOIC (suffix L)  
The A4401 is supplied in an 8-pin narrow SOIC package  
(suffix L), which is lead (Pb) free, with 100% matte-tin  
leadframe plating.
