NB650HGL-Z Equivalent & Substitute Parts

Part Overview

The NB650HGL-Z is a buck switching regulator IC manufactured by Monolithic Power Systems Inc., designed for step-down voltage conversion applications. This positive adjustable output PMIC delivers 6A continuous current with an input voltage range of 4.5V to 22.5V and adjustable output from 0.6V to 13V. The device is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design continuity across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NB650HGL-Z is determined by strict equivalence across the following critical parameters:

• Functional topology: Step-down buck converter with positive adjustable output
• Electrical specifications: Input voltage range 4.5V–22.5V, output range 0.6V–13V, 6A output current capability
• Switching frequency: 150kHz–1MHz operation
• Synchronous rectification: Integrated synchronous rectifier present
• Package compatibility: 17-VFQFN Exposed Pad form factor
• Compliance certifications: RoHS3 compliance and MSL 1 rating
• Manufacturer: Monolithic Power Systems Inc. (same manufacturer ensures design continuity)

The NB650AGL-Z meets all substitution criteria as a direct equivalent part from the same manufacturer and product series.

Parameter Comparison

Engineering Selection Recommendations

The NB650AGL-Z is a direct substitute for the NB650HGL-Z. Both parts are manufactured by Monolithic Power Systems Inc., share identical electrical and thermal specifications, and are packaged in the same 17-VFQFN Exposed Pad form factor. Both parts maintain active product status and full RoHS3 compliance with MSL 1 rating. The primary difference is packaging format: NB650HGL-Z is supplied in standard packaging, while NB650AGL-Z is supplied in cut tape (CT) format. This distinction affects only procurement and handling procedures, not electrical performance or circuit compatibility. Selection between these parts should be based on packaging requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can NB650AGL-Z replace NB650HGL-Z in existing designs? A: Yes. Both parts are electrically and mechanically identical. They share the same die, electrical specifications, operating range, and package footprint. No circuit modifications are required.

Q: What is the difference between NB650HGL-Z and NB650AGL-Z? A: The difference is packaging format only. NB650HGL-Z uses standard packaging, while NB650AGL-Z uses cut tape (CT) format. Electrical performance and pinout are identical.
