Texas Instruments TPS61022EVM-034

Overview

TPS61022EVM-034 from Texas Instruments is an evaluation module designed to characterize the TPS61022 8-A boost converter with 0.5-V ultra-low input voltage capability, supporting input ranges from 0.5 V to 5.5 V and delivering up to 3 A output current at VIN = 2.7 V. It includes full schematic, BOM, four-layer PCB layout, and test-ready jumpers for MODE/EN control and voltage sensing.

For engineers reviewing the TPS61022EVM-034 datasheet, TPS61022EVM-034 setup, TPS61022EVM-034 schematic, or TPS61022EVM-034 BOM, this module enables rapid validation of high-current boost performance under low-input-voltage conditions (e.g., single-cell Li-ion, NiMH, or energy-harvesting sources), loop stability with feedforward capacitor tuning, and efficiency measurement across load and input voltage sweeps.

Technical Context

The TPS61022EVM-034 implements the TPS61022 in a fully assembled, test-optimized configuration with dedicated input/output sensing terminals (J7, J8), selectable PFM/PWM operation via J5, and enable control via J6. It supports real-time modification of external components including feedback resistors (R1, R2), feedforward capacitor (C8 - DNP by default), and output capacitance.

Tested at 25°C ambient, the EVM delivers 5.1 V output at 3.6 V input and ≤3 A load, with validated phase margin improvement (63° vs. 44°) when adding a 10-pF feedforward capacitor at 1.8 V input. Its four-layer board features internal ground planes for thermal management and EMI suppression, matching TI's reference design practices for high-current DC/DC evaluation.

FAQ

What is the primary function of the TPS61022EVM-034?

The TPS61022EVM-034 is an evaluation module used to assess the electrical performance, stability, and thermal behavior of the TPS61022 8-A boost converter. It provides accessible test points, configurable operating modes, and a production-representative PCB layout to validate design parameters before integration into end equipment.

Does the TPS61022EVM-034 include the TPS61022 IC?

Yes, the TPS61022EVM-034 includes one TPS61022RWUR IC (VQFN-HR-7 package) pre-soldered onto the board. The IC is mounted per TI's recommended layout guidelines and operates as the core switching regulator in the evaluation circuit.

How do I configure the TPS61022EVM-034 for forced PWM mode?

To configure the TPS61022EVM-034 for forced PWM mode, place a jumper across pins 1 and 3 of header J5 (MODE), connecting the MODE pin to VIN. This overrides automatic PFM/PWM transition and maintains constant switching frequency across all load conditions.

Can the TPS61022EVM-034 be used with input voltages below 1.8 V?

Yes - the TPS61022EVM-034 supports input voltages down to 0.5 V per the TPS61022 specification. At sub-2-V inputs, TI recommends populating the C8 feedforward capacitor (e.g., 10 pF) to maintain loop stability, as demonstrated by the 63° phase margin achieved at 1.8 V input on the TPS61022EVM-034.

Where can I find the schematic and BOM for the TPS61022EVM-034?

The complete schematic, bill of materials (BOM), top/bottom PCB layouts, and test data for the TPS61022EVM-034 are published in the official TI User's Guide SLVUBJ7 (January 2019), which is freely available on ti.com - all documents are specific to the TPS61022EVM-034 part number and not generic to other EVMs.
