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

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.
