PT6470 Series  
14-A 3.3-V Input Adjustable  
Integrated Switching Regulator  
SLTS180A - JANUARY 2003 - REVISED JUNE 2003  
Features  
• 3.3 V Input  
• Over-Current Protection  
• Output Remote Sense  
• Optional Output Capacitor  
• Small Footprint  
• 14 A Output Current  
• Low-Profile (8mm)  
• DSP Compatible  
• High Efficiency (Up to 95%)  
• Adjustable Output Voltage  
• On/Off Inhibit Function  
• Pre-Bias Start-up Capability  
(0.64 in², Suffix ‘N’)  
• Surface Mount Compatible  
• IPC Lead Free 2  
Description  
Pin-Out Information  
Ordering Information  
Pin Function  
PT6472r = 2.5 Volts  
PT6473r = 2.0 Volts  
PT6474r = 1.8 Volts  
PT6475r = 1.5 Volts  
PT6476r = 1.2 Volts  
PT6477r = 1.0 Volts  
The PT6470 Excalibur™ series of integrated  
switching regulators (ISRs) combines outstand-  
ing power density with a comprehensive list of  
features. They are an ideal choice for applications  
where board space is a premium and performance  
cannot be compromised. These modules provide a  
full 14 A of output current, yet are housed in a  
low-profile, 12-pin, package that is almost half  
the size of the previous generation of products.  
The integral copper case construction requires  
no heatsink, and offers the advantages of solder-  
ability and a small footprint (0.64 in² for suffix  
‘N’). Both through-hole and surface mount pin  
configurations are available.  
The PT6470 series operates from a 3.3-V  
input to provide a convenient point-of-load power  
source for the industry’s latest high-performance  
DSPs and microprocessors. The series includes  
output voltage options as low as 1.0V DC.  
Other features include external output voltage  
adjustment, on/off inhibit, pre-bias startup, short  
circuit protection, and an output remote sense.
