SP7662  
PowerbloxTM  
12A 300KHz Synchronous Step Down Regulator  
Rev. 2.1.0  
September 2012  
GENERAL DESCRIPTION  
APPLICATIONS  
The SP7662 is a synchronous voltage mode  
PWM step down (buck) regulator capable of a  
constant output current up to 12 Amps. A wide  
5V to 22V single input voltage range allows for  
single supply operations from industry  
standard 5V, 12V and 18V power rails.  
Operations down to 3V are supported with an  
additional biasing voltage.  
ñ Distributed Power Architectures  
ñ Point of Load Converters  
ñ Power Supply Modules  
ñ FPGAs, DSPs and Processors Supplies  
FEATURES  
With a 300kHz constant operating frequency  
and integrated high and low side switch, the  
SP7662 reduces the overall component count  
and solution footprint. In addition to a 1%  
output setpoint accuracy, this device provides  
high efficiency, low ripple and excellent line  
and load regulation. An enable function and  
soft start feature allow for controlled power up  
sequencing implementation.  
ñ 12A Continuous Current  
ñ 5V-22V Single Input Voltage Rail  
- 3V-22V Input Voltage with 5V Bias  
ñ PWM Voltage Mode Control  
- 300kHz Fixed Synchronous Operations  
- Low RDSON Power Switches  
- 0.8V Min. Output Voltage 1% Accuracy  
Built-in current limiting, UVLO, output short-  
circuit and over temperature protection insure  
safe operation under abnormal operating  
conditions.  
ñ Type II & III Compensations Support  
ñ Programmable Soft Start  
ñ Over Temperature & Short Circuit  
Protection/Auto-Restart  
The SP7662 is offered in a RoHS compliant,  
lead free 26-pin 7mmx4mm DFN package.  
ñ Current Limiting  
ñ RoHS Compliant Lead Free 26-Pin DFN  
ñ US Patent #6,922,041
