Texas Instruments TLVM23625EVM

Overview

TLVM23625EVM from Texas Instruments is an evaluation module designed to assess the TLVM23625 36-V input, 1-V to 6-V output, 2.5-A DC-DC power module in buck regulator applications. It supports configurable output voltage (1.8 V–6 V), adjustable switching frequency (500 kHz–3 MHz), and features programmable enable UVLO, power-good flag, and frequency foldback mode. The EVM enables efficiency measurement, loop response analysis, and thermal performance validation under real load conditions up to 2.5 A.

For engineers reviewing the TLVM23625EVM datasheet, TLVM23625EVM test setup, TLVM23625EVM layout, or TLVM23625EVM jumper configuration, this page delivers verified evaluation capabilities, PCB layer stack-up details, test point mapping, and application-specific configuration guidance for rapid prototyping of compact, high-efficiency point-of-load supplies.

Technical Context

The TLVM23625EVM implements the TLVM23625RDNR - a QFN-FCMOD11 packaged, integrated power module with internal MOSFETs, controller, and shielded inductor. It supports auto-mode (frequency foldback at light load) and externally synchronized operation via TP7/TP8, with configurable EN/UVLO thresholds using R2/R4.

Test points TP1–TP12 and jumpers J3 (VOUT), J4 (Fsw), and J5 (disable) provide direct access to VIN, VOUT, PGOOD, EN, and AC injection nodes. The 4-layer PCB includes dedicated ground plane (top layer), primary routing (mid-layer 1), PI filter section (mid-layer 2), and bottom-side input capacitor placement optimized for low loop inductance and thermal dissipation.

FAQ

What is the default output voltage and switching frequency setting on the TLVM23625EVM?

The TLVM23625EVM ships pre-configured with a 5-V output voltage (via J3 jumper position) and 2.2-MHz switching frequency (via J4 pins 3–4), operating in auto mode with frequency foldback at light load. These defaults are documented in Section 1 of the SLVUCK5 User's Guide and verified using TP3/TP6 and oscilloscope measurements on TP7/TP8.

How do I disable the TLVM23625 regulator on the TLVM23625EVM?

To disable the TLVM23625 regulator on the TLVM23625EVM, short the two pins of jumper J5 as specified in Table 3-1 of the User's Guide. This grounds the EN pin internally, forcing the TLVM23625RDNR into shutdown state with near-zero quiescent current draw and no switching activity.

Which test points on the TLVM23625EVM are used to measure PGOOD functionality?

TP4 is the dedicated test point for measuring the PGOOD (power-good) flag output of the TLVM23625 on the TLVM23625EVM. It connects directly to the U1 PGOOD pin and provides a clean, low-capacitance node for logic-level verification using a DVM or oscilloscope during startup, regulation, and fault conditions.

Can the TLVM23625EVM be synchronized to an external clock source?

Yes - the TLVM23625EVM supports external synchronization via test points TP7 and TP8, which connect directly to the RT/SYNC pin of the TLVM23625RDNR. Applying a clean CMOS/TTL clock signal within the supported frequency range (500 kHz–3 MHz) overrides internal oscillator operation and aligns switching edges to the external source.

What is the purpose of the PI filter section (J1) on the TLVM23625EVM?

The PI filter section (J1 input terminal block and associated C5 damping capacitor) on the TLVM23625EVM is intended for conducted EMC compliance testing per CISPR 11/32 standards. It attenuates differential-mode noise at the switching frequency and harmonics, enabling pre-compliance scans without modifying the core TLVM23625 circuitry.
