For engineers reviewing the LMR64010XMFDEMO/NOPB datasheet, LMR64010XMFDEMO/NOPB application, or LMR64010XMFDEMO/NOPB equivalent, this page delivers verified board-level specifications, input/output behavior under load, shutdown control interface, output voltage adjustability, feedforward compensation guidance, and measured efficiency/ripple performance - all critical for power supply validation and schematic review.

Technical Context

The LMR64010XMFDEMO/NOPB implements a fixed-frequency current-mode boost topology using the LMR64010 IC, which integrates a 40V/1A internal N-channel MOSFET switch and 1.23V feedback reference. It supports 2.7V–12V input and delivers up to 24V at 125mA from 5V input, with 1.6MHz operation enabling compact external components.

Board-level design includes feedforward compensation (CF = 120pF), output voltage set via R1/R2 divider (243kΩ/13.3kΩ), EN-controlled shutdown, and optimized layout for low-noise measurement - validated by TI's published efficiency curves, load transient waveforms, and ripple data at 23.5–23.7V output.

FAQ

What is the primary function of the LMR64010XMFDEMO/NOPB?

The LMR64010XMFDEMO/NOPB is a ready-to-use evaluation board that demonstrates the LMR64010 boost regulator IC in operation. It delivers a regulated 24V output from a 5V input, supporting up to 125mA load current at 1.6MHz switching frequency. The board includes test points, enable control, and adjustable feedback resistors - allowing engineers to validate performance, measure efficiency, and verify system integration before final design. LMR64010XMFDEMO/NOPB does not contain the LMR64010 IC as a standalone component but hosts it as the core active device on the PCB.

Can the output voltage of the LMR64010XMFDEMO/NOPB be adjusted?

Yes, the output voltage of the LMR64010XMFDEMO/NOPB can be adjusted using the feedback resistor divider network (R1 and R2). The default configuration uses 243kΩ and 13.3kΩ to set 24V output based on the LMR64010's 1.23V internal reference (VOUT = 1.23V × (1 + R1/R2)). Engineers may replace R1 to achieve other voltages while maintaining stability - TI recommends recalculating the feedforward capacitor (CF = 1/(2π × 8kHz × R1)) for optimal transient response. LMR64010XMFDEMO/NOPB supports this reconfiguration without board modification.

How is shutdown controlled on the LMR64010XMFDEMO/NOPB?

Shutdown on the LMR64010XMFDEMO/NOPB is implemented via the EN (Enable) test point. The board includes a 1MΩ pull-up resistor (R3) that keeps the LMR64010 enabled when EN is left floating or connected to VIN. To disable the regulator, the EN node must be pulled to GND - either manually with a jumper or via an external logic signal. This allows precise startup/shutdown timing verification and power sequencing tests. LMR64010XMFDEMO/NOPB provides direct access to this control node through a yellow Keystone test loop.

What are the key performance metrics measured on the LMR64010XMFDEMO/NOPB?

TI's AN-2183 user guide documents key performance metrics for the LMR64010XMFDEMO/NOPB, including efficiency vs. load current (up to 85% at 125mA/24V from 5V input), output voltage ripple (<50mVpp typical), load transient response (13–125mA step), and startup waveform fidelity. These measurements were captured using calibrated equipment and published in Figures 11–16. LMR64010XMFDEMO/NOPB serves as the physical platform used to generate those validated results - making it essential for correlating simulation with real-world behavior.

Is the LMR64010XMFDEMO/NOPB compatible with the LMR62014 demo board?

No, the LMR64010XMFDEMO/NOPB is not electrically or mechanically interchangeable with the LMR62014 demo board, though both share identical form factor and layout structure. They differ in key component values: LMR64010XMFDEMO/NOPB uses CRS04 Schottky diode (40V/1.0A), 243kΩ R1, and 120pF CF, while the LMR62014 version uses CRS08 (30V/1.5A), 115kΩ R1, and 220pF CF. These changes reflect the distinct 24V/125mA vs. 12V/450mA output targets. LMR64010XMFDEMO/NOPB is specifically optimized for the LMR64010 IC and its higher-voltage operating point.
