DESCRIPTION

The PTR08060W is a highly integrated, low-cost switching regulator module that delivers up to 6 A of output

current. Occupying approximate PCB area of a standard TO-220 linear regulator IC, the PTR08060W provides

output current at a much higher efficiency and with much less power dissipation, thereby eliminating the need for

a heat sink. Their small size (0.65 x 0.41 in), high efficiency, and low cost makes these modules attractive for a

variety of applications.

The input voltage range of the PTR08060W is from 4.5 V to 14 V, allowing operation from either a 5-V or 12-V

input bus. Using state-of-the-art switched-mode power-conversion technology, the PTR08060W can step down to

voltages as low as 0.6 V. The output voltage can be adjusted to any voltage over the range, 0.6 V to 5.5 V, using

a single external resistor. Operating features include an undervoltage lockout (UVLO), on/off inhibit and output

overcurrent protection. Target applications include servers, test and measurement applications, and high-end

consumer products.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.

PTR08060W www.ti.com SLTS289G – AUGUST 2007 – REVISED MARCH 2013 Power-Up Characteristics When configured per the standard application, the PTR08060W power module produces a regulated output voltage following the application of a valid input source voltage. During power up, internal soft-start circuitry slows the rate that the output voltage rises, thereby limiting the amount of in-rush current that can be drawn from the input source.
