TPS61235RWLR Equivalent & Substitute Parts

Part Overview

The TPS61235RWLR is a boost switching regulator IC from Texas Instruments designed for power management applications. It delivers a fixed 5.1V output with 6.5A switch current capability, operating from a 2.3V to 4.5V input range. The device features synchronous rectification and operates at 1MHz switching frequency in a compact 9-VFQFN surface mount package.

The TPS61235RWLR is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this boost regulator topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS61235RWLR is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Input voltage range (2.3V to 4.5V), fixed output voltage (5.1V), output current capability (6.5A switch), switching frequency (1MHz), and synchronous rectifier topology must remain identical.

Mechanical Compatibility: Package type (9-VFQFN) and mounting method (surface mount) must match to ensure PCB layout compatibility without redesign.

Regulatory Compliance: RoHS3 compliance status must be maintained for applications subject to environmental regulations.

The TPS61235PRWLR qualifies as a direct substitute based on identical electrical specifications, package configuration, and regulatory compliance. The primary distinction is product status and operating temperature range, which do not affect functional equivalence for the specified boost regulator application.

Parameter Comparison

Engineering Selection Recommendations

The TPS61235PRWLR is the direct substitute for the obsolete TPS61235RWLR. Both devices share identical electrical specifications, package configuration, and regulatory compliance status. The TPS61235PRWLR maintains active product status with improved availability and extended operating temperature range (-40°C to 125°C junction temperature versus -40°C to 85°C ambient for the original part).

For applications currently using the TPS61235RWLR, transition to the TPS61235PRWLR requires no circuit redesign. The devices are pin-compatible, functionally equivalent, and maintain ROHS3 compliance and REACH unaffected status. The extended temperature rating of the substitute part provides additional operational margin for demanding thermal environments.

Frequently Asked Questions (FAQ)
