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.

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.
