Texas Instruments LMZ30602EVM-002

Overview

LMZ30602EVM-002 from Texas Instruments is a dedicated evaluation module for the LMZ30602 synchronous buck power module, supporting 2.95–6-V input and 2-A output with PWM control. It enables rapid characterization of efficiency, load/line regulation, transient response, and thermal performance in 3.3-V and 5-V bus applications. The board features configurable output voltage (0.8 V to 3.3 V) and switching frequency (650 kHz to 1.5 MHz) via hardware jumpers.

For engineers reviewing the LMZ30602EVM-002 datasheet, LMZ30602EVM-002 pinout, LMZ30602EVM-002 application, or LMZ30602EVM-002 equivalent, this EVM provides direct access to PWRGD, INH/UVLO, RT/CLK, and SS/TR control signals; full-current test points for VIN/VOUT ripple and scope measurements; and a thermally optimized PCB layout aligned with TI's recommended design practices.

Technical Context

The LMZ30602EVM-002 implements the LMZ30602RKG QFN-based power module in a fixed 2-A configuration, with factory-set UVLO threshold (~3.05 V) and soft-start time (~1 ms). It supports five output voltages (0.8 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V) and four switching frequencies (650 kHz, 750 kHz, 1 MHz, 1.5 MHz), selected via dual jumper banks.

All critical device pins-including PH, BOOT, PWRGD, INH/UVLO, RT/CLK, and SS/TR-are exposed as test points with defined grounding schemes (VIN/VOUT monitor GNDs and control GNDs). Input and output capacitance uses Murata GRM32ER6-series ceramics and Sanyo polymer capacitors, matching TI's reference design recommendations for stability and low ESR.

FAQ

What is the primary function of the LMZ30602EVM-002?

The LMZ30602EVM-002 is a Texas Instruments evaluation module specifically configured for the LMZ30602 2-A synchronous buck power module. Its purpose is to accelerate design-in by enabling immediate testing of efficiency, transient response, thermal behavior, and control-loop features-including PWRGD monitoring, UVLO adjustment, frequency synchronization, and soft-start tuning-without requiring custom PCB development. The LMZ30602EVM-002 is not a production-ready power supply but a validated lab tool.

Which output voltage and switching frequency combinations are supported on the LMZ30602EVM-002?

The LMZ30602EVM-002 supports five output voltages (0.8 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V) and four switching frequencies (650 kHz, 750 kHz, 1 MHz, 1.5 MHz), with specific pairings documented in Table 2 of the SNVU296A User's Guide. For example, 0.8 V output uses 650 kHz, while 3.3 V uses 1.5 MHz. These settings are selected using two physical jumpers before power application, and all combinations are verified for stable operation across the LMZ30602's input range (2.95–6 V).

How does the LMZ30602EVM-002 expose control signals like PWRGD and INH/UVLO?

The LMZ30602EVM-002 exposes PWRGD and INH/UVLO as labeled test points (TP14 and TP12, respectively) with clearly defined grounding references. PWRGD is an open-drain signal requiring an external pull-up (10–100 kΩ to VIN); it asserts high when VOUT is within ±8% of nominal. INH/UVLO connects directly to the device's inhibit/UVLO pin: grounding it disables the converter, while floating enables operation. The LMZ30602EVM-002 also includes a resistor network option to raise the UVLO threshold beyond the default 3.05 V.

Can the LMZ30602EVM-002 be used to evaluate other LMZ3060x devices?

No-the LMZ30602EVM-002 is physically populated with the LMZ30602RKG device and calibrated for its 2-A current capability, thermal profile, and parameter ranges. While the board shares the same PCB footprint and jumper architecture as the LMZ30604EVM-001 and LMZ30606EVM-003, substituting another LMZ3060x device requires verifying compatibility with the existing input/output capacitor selection, thermal layout, and current-sense path. The LMZ30602EVM-002 user guide explicitly states it is configured for the LMZ30602 only.

What safety and compliance information applies to the LMZ30602EVM-002?

The LMZ30602EVM-002 is classified as a Class A digital device compliant with FCC Part 15 and ICES-003 regulations. It is intended solely for laboratory evaluation-not end-product integration-and carries explicit disclaimers prohibiting consumer use, incorporation into finished goods, or operation outside specified voltage/current/thermal limits. Users must follow TI's safety instructions, including using appropriate grounding for test equipment, avoiding high-current connections to monitoring test points, and observing maximum case temperature warnings for components like the LMZ30602RKG during operation.
