TPS62050DGSG4 Equivalent & Substitute Parts

Part Overview

The TPS62050DGSG4 is a buck switching regulator IC from Texas Instruments designed for positive adjustable voltage regulation. It delivers up to 800mA output current with an input voltage range of 2.7V to 10V and adjustable output voltage from 0.7V to 6V. The device operates at a switching frequency of 850kHz and includes a synchronous rectifier for improved efficiency.

The TPS62050DGSG4 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS62050DGSG4 is determined by strict equivalence across the following critical parameters:

• Topology & Function: Buck (step-down) switching regulator with positive adjustable output
• Electrical Specifications: Input voltage range 2.7V–10V, adjustable output 0.7V–6V, 800mA output current capacity
• Switching Frequency: 850kHz operation
• Synchronous Rectifier: Integrated synchronous rectification capability
• Package Compatibility: 10-TFSOP/10-MSOP surface mount package (0.118", 3.00mm width)
• Operating Temperature Range: -40°C to 125°C junction temperature
• Compliance: RoHS3 compliance, REACH unaffected status

The TPS62050DGS meets all these criteria and is therefore a direct functional and electrical equivalent.

Parameter Comparison
