Range: –40°C to 85°C Space Saving Vertical SIP Package Instrumentation Consumer Electronics Servers General-Purpose Circuits DESCRIPTION The PTR08100W is a highly integrated, low-cost switching regulator module that delivers up to 10 A of output current. Occupying approximate PCB area of a standard TO-220 linear regulator IC, the PTR08100W 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 PTR08100W 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 PTR08100W 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.

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. A small low-leakage (
