A6210  
3 A, 2 MHz Buck-Regulating LED Driver  
Features and Benefits  
Description  
▪ User-configurable on-time, achieving switching  
frequencies up to 2.0 MHz  
The A6210 is a buck regulator that uses valley current-mode  
control.Thiscontrolschemeallowsveryshortswitchon-times  
to be achieved, making it ideal for applications that require  
high switching frequencies combined with high input voltages  
and low output LED span voltages.  
▪ Brightness control through PWM of DIS pin  
▪ Minimal external components required  
▪ No output capacitor required  
▪ Wide input voltage range: 9 to 46 V  
▪ Low 0.18 V sense voltage for higher efficiency  
▪ Output Current: up to 3.0 A  
▪ Low standby current <100 μA  
▪ Thermal shutdown  
Low system cost is accomplished through high switching  
frequenciesofupto2.0MHz,allowingsmallerandlowervalue  
inductorsandcapacitors.Inaddition,fewexternalcomponents  
are required through high levels of integration. Optimal drive  
circuits minimize switching losses.  
▪ Supplied in a thermally-enhanced 4 mm QFN package  
Theswitchingfrequencyismaintainedconstant,astheon-time  
is modulated by the input voltage. This feed-forward control  
ensures excellent line correction. The on-time is set by an  
external resistor pulled-up to the input supply.  
Applications:  
▪ High brightness LEDs  
▪ LED driver modules, power supplies and lamps, such as  
MR16 and MR11  
Internal housekeeping and bootstrap supplies are provided  
whichrequiretheadditionofonlyonesmallceramiccapacitor.A  
top-off charge pump ensures correct operation at light loads.  
Package 16-contact QFN (suffix EU):  
Internaldiagnosticsprovidecomprehensiveprotectionagainst  
input undervoltages and overtemperatures.  
The device package is a 16-contact, 4 mm × 4 mm, 0.75 mm  
nominal overall height QFN, with exposed pad for enhanced  
thermal dissipation. It is lead (Pb) free, with 100% matte tin  
leadframe plating.
