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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
ORDERING INFORMATION
For the most current package and ordering information, see the Package Option Addendum at the end of this datasheet, or see

For output voltages less than 1.0 V, the output ripple may increase (up to 2×) when operating at input voltages greater than (VO ×15).
The minimum input voltage is 4.5 V or (VO/0.83) V, whichever is greater.
The set-point voltage tolerance is affected by the tolerance and stability of RSET. The stated limit is unconditionally met if RSET has a
tolerance of 1% with with 100 ppm/°C or better temperature stability.
This control pin has an internal pullup to the input voltage VI. If it is left open circuit, the module operates when input power is applied.
The open pin voltage is 2.8 V (typ). A small low-leakage (
