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  
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.  
• 5-Pin Mount Option  
(Suffixes L & M)

Notes: (1) The ISR will operate at no load with reduced specifications.  
(2) Boost topology ISRs are not short circuit protected.  
(3) The inrush current stated is above the normal input current for the associated output load.  
(4) See Safe Operating Area curves or consult the factory for the appropriate derating  
(5) The tab pins on the 5-pin mount package types (suffixes L & M) must be soldered. For more information see the applicable package outline drawing.
