PT5040 Series
1-A Positive Step-up Integrated Switching Regulator
SLTS026B
(Revised 12/19/2001)
Features
· Wide Input Voltage Range · 85% Efficiency · Internal Over-Temperature Protection · Laser-trimmed Output Voltage · Soft Start · 5-Pin Mount Option (Suffixes L & M)
Description
The PT5040 is a series of 3-pin boost-voltage Integrated Switching Regulators (ISRs). These ISRs are designed for use with +5V bus systems that require an additional regulated +8V to +20V with up to 1A of output current. These ISRs are packaged in the 3-pin, single in-line pin (SIP) package configuration.

The ISR will operate at no load with reduced specifications. Boost topology ISRs are not short circuit protected. The inrush current stated is above the normal input current for the associated output load. See Safe Operating Area curves or consult the factory for the appropriate derating The tab pins on the 5-pin mount package types (suffixes L & M) must be soldered.
