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. For more information see the applicable package outline drawing.

The marketing status values are defined as follows:

ACTIVE:

Product device recommended for new designs.

LIFEBUY:

TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

NRND:

Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.

PREVIEW:

Device has been announced but is not in production. Samples may or may not be available.

OBSOLETE:

TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check

http://www.ti.com/productcontent

for the latest availability

information and additional product content details.

TBD:

The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS):

TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that

lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Pb-Free (RoHS Exempt):

This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between

the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.

Green (RoHS & no Sb/Br):

TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight

in homogeneous material)

(3)

MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
