What are the key features of LM21215MHX/NOPB?
- High-current synchronous buck converter delivering up to 15 A continuous output current from a 2.95 V to 5.5 V input supply
- Adjustable output voltage from 0.6 V to 5.5 V using voltage-mode PWM control, covering a wide range of digital core and I/O rail requirements
- Compact 20-pin HTSSOP exposed-pad package with integrated power switches, minimizing external component count for space-constrained power stages
What is LM21215MHX/NOPB used for?
The LM21215MHX/NOPB is designed for point-of-load power conversion on high-density server blades, FPGA and DSP boards, and network switching equipment where 15 A at sub-1 V core voltages is required from a 5 V bus. Its adjustable 0.6 V to 5.5 V output allows a single design to power both processor core rails and peripheral I/O rails. The synchronous topology delivers high efficiency across load transients typical in data-center applications.

Frequently Asked Questions
What is the maximum output current of the LM21215MHX/NOPB and at what input voltage does it achieve it?
The LM21215MHX/NOPB delivers up to 15 A continuous output current when supplied from 2.95 V to 5.5 V input. Peak efficiency is typically achieved near 5 V input with an output set between 1 V and 3.3 V, making it a strong candidate for FPGA core and DDR memory rail designs.
How low can the output voltage be set on the LM21215MHX/NOPB, and which processor core rails does that cover?
The output is adjustable down to 0.6 V via an external resistor divider, which covers sub-1 V core voltages demanded by modern FPGAs and ARM Cortex processors. Combined with the 15 A current rating, this allows powering core rails as low as 0.9 V for high-performance compute silicon.
How does voltage-mode PWM control in the LM21215MHX/NOPB compare to current-mode control for transient response?
Voltage-mode PWM control in the LM21215MHX/NOPB responds to output voltage deviations with a fixed switching frequency, providing predictable EMI spectrum and simpler compensation design. While current-mode offers faster cycle-by-cycle limiting, voltage-mode with a type-III compensator can achieve load-step response within a few microseconds at 15 A, which is sufficient for most digital-load applications.
What package does the LM21215MHX/NOPB use and how does the exposed pad affect thermal management?
It uses a 20-pin HTSSOP package with an exposed thermal pad on the underside, allowing direct soldering to a PCB copper pour. This reduces junction-to-board thermal resistance to approximately 5 °C/W to 8 °C/W with proper via stitching, enabling the 15 A rating to be sustained without external heatsinks in typical server and networking environments.
