Texas Instruments TLVM13660EVM

Overview

TLVM13660EVM from Texas Instruments is a fully assembled, 4-layer evaluation module built around the TLVM13660 synchronous buck power module - a 36-V, 6-A integrated DC/DC solution with embedded MOSFETs, inductor, and PWM controller. It supports input voltages from 3 V to 36 V, adjustable output voltages (1.2 V to 5 V or –5 V), and switching frequencies from 500 kHz to 1 MHz. The EVM enables rapid validation of high-density, low-EMI power designs in industrial and test equipment applications.

For engineers reviewing the TLVM13660EVM datasheet, TLVM13660EVM test setup, TLVM13660EVM jumper configuration, or TLVM13660EVM thermal performance, this page delivers verified electrical specifications, jumper-based voltage/frequency selection logic, CISPR 32 Class B EMI compliance data, efficiency curves across load and input conditions, and practical guidance for load transient, Bode plot, and PGOOD sequencing measurements.

Technical Context

The TLVM13660EVM implements a peak current-mode controlled buck topology using the TLVM13660 module, which integrates power MOSFETs, a shielded buck inductor, and compensation circuitry. It supports both standard buck (positive VOUT) and inverting buck-boost (IBB) configurations, enabling –5 V output with up to 4 A output current under IBB operation.

Key design features include resistor-programmable UVLO (5.1 V turn-on / 3.65 V turn-off), open-drain PGOOD with internal 100-kΩ pullup to VOUT, FPWM mode for constant-frequency operation across full load range, and integrated input/VCC/CBOOT capacitors to minimize high-di/dt loop area and reduce radiated emissions.

FAQ

What is the default output voltage and switching frequency configured on the TLVM13660EVM?

The TLVM13660EVM ships with a default output voltage of 5 V and a default switching frequency of 1 MHz, set via factory-installed jumpers on headers J3 and J4. These settings can be changed to alternate voltages (1.2 V, 1.8 V, 2.5 V, 3.3 V, or –5 V) and frequencies (500 kHz to 1 MHz) by repositioning the jumpers - no soldering or component replacement required. The TLVM13660EVM user guide provides exact jumper maps for each combination.

How does the TLVM13660EVM support inverting buck-boost (IBB) operation?

The TLVM13660EVM supports IBB topology by reconfiguring terminal connections: the input source is applied between VIN+ and VOUT+, producing a regulated –5 V output referenced to PGND. In this mode, the achievable output current is IOUT = 6 A × (1 – D), where D = |VOUT|/(VIN + |VOUT|). At VIN = 12 V, this yields ~4 A; at VIN = 24 V, ~3.3 A. The TLVM13660EVM schematic and User's Guide Section 1.1 confirm this wiring and derating behavior.

What test points and interfaces are accessible on the TLVM13660EVM for performance validation?

The TLVM13660EVM provides dedicated sense terminals (VIN S+, VIN S–, VOUT S+, VOUT S–) for accurate efficiency and regulation measurements, plus header J5 offering direct access to VIN, PGND, EN, PGOOD, VOUT, and BODE signals. The BODE test point enables loop gain measurement when used with a 10-Ω injection resistor. All interfaces comply with standard lab instrumentation practices and are documented in Tables 4-1 and 4-2 of the TLVM13660EVM User's Guide.

Does the TLVM13660EVM meet international EMI standards, and how is compliance achieved?

Yes, the TLVM13660EVM meets CISPR 32 Class B limits for both conducted and radiated emissions, as verified in Figures 5-25 through 5-30 of its User's Guide. Compliance is achieved through an integrated π-stage input EMI filter, symmetrical parallel input/output capacitor layouts, FPWM operation for predictable spectral content, and on-module integration of input, VCC, and CBOOT capacitors - all minimizing high-di/dt loop area without external filtering components.

What thermal performance can be expected from the TLVM13660EVM under full-load conditions?

Under full-load (6 A), the TLVM13660EVM achieves junction temperatures ≤125°C and ambient ratings up to +105°C, validated via infrared thermal imaging across multiple VIN/VOUT/FSW combinations (e.g., Figure 5-13: 12 V_IN/5 V_OUT/6 A/1 MHz shows hotspot ~95°C). Derating curves (Figures 5-19–5-24) define safe operating current vs. ambient temperature, confirming suitability for convection-cooled industrial enclosures with ≥200 LFM airflow above 4 A.
