PT6470 Series 14-A 3.3-V Input Adjustable Integrated Switching Regulator SLTS180A - JANUARY 2003 - REVISED JUNE 2003 Features 3.3 V Input 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 Over-Current Protection Output Remote Sense Optional Output Capacitor Small Footprint (0.64 in², Suffix ‘N’) Surface Mount Compatible IPC Lead Free 2 Description The PT6470 Excalibur™ series of integrated switching regulators (ISRs) combines outstanding 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 solderability 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 outp...
