PT6600_14 Datasheet, PDF (1/9 Pages) Texas Instruments – Single Device 9A Output

PT6600 Series
9 Amp 5V/3.3V Input Adjustable
Integrated Switching Regulator
SLTS035A
(Revised 6/30/2000)
• Single Device 9A Output
• Input Voltage Range: 3.1V to 6.0V
• Adjustable Output Voltage
• 90% Efficiency
• Remote Sense Capability
• Standby Function
• Over-Temperature Protection
The PT6600 series is a high per-
formance family of 14-Pin SIP (Single
In-line Package) Integrated Switching
Regulators (ISRs), designed for stand-
alone operation in applications
requiring as much as 9A of output
current.
The PT6600 series will operate
off either a 3.3V or 5V input bus and
requires only two external capacitors
for proper operation. Please note that
this product does not include short
circuit protection.
