Texas Instruments TPS61070EVM-062

Overview

TPS61070EVM-062 from Texas Instruments is an evaluation module built around the TPS61070DDC SOT23-6 boost converter IC, configured to deliver a regulated 5-V output at up to 300 mA from input sources as low as 0.9 V - ideal for single-cell alkaline or Li-ion battery-powered portable electronics.

For engineers reviewing the TPS61070EVM-062 datasheet, TPS61070EVM-062 pinout, TPS61070EVM-062 application, or TPS61070EVM-062 equivalent, this EVM supports rapid validation of high-efficiency, space-constrained boost power stages in ultra-low-voltage battery systems, with documented test data, BOM, and layout guidance included.

Technical Context

The TPS61070EVM-062 implements a fixed 5-V output configuration using the TPS61070DDC - a current-mode DC/DC boost converter with integrated 0.35-Ω switch, 0.4-A current limit, and 1.2-MHz switching frequency. It operates across 0.9 V to 5.5 V input, enabling direct use with partially discharged alkaline cells.

Board-level design includes Coilcraft MSS4020-472MX (4.7 µH) inductor, TDK C2012X5R0J106KT (10 µF) input capacitor, and precision feedback resistors (R1 = 909 kΩ, R2 = 100 kΩ) setting V_OUT = 5 V. Layout follows TI's HPA062 PWB reference design with isolated high-frequency switching nodes.

FAQ

What is the primary function of the TPS61070EVM-062?

The TPS61070EVM-062 is an evaluation module that demonstrates the TPS61070DDC boost converter IC in a fixed 5-V output configuration. It enables engineers to validate performance - including efficiency, regulation, and transient response - when stepping up voltages from 0.9 V to 5.5 V, particularly for single-cell battery applications. The TPS61070EVM-062 includes full schematic, BOM, and test data to support design-in decisions.

Does the TPS61070EVM-062 support adjustable output voltage?

No - the TPS61070EVM-062 is configured for a fixed 5-V output using a precision resistor divider (R1 = 909 kΩ, R2 = 100 kΩ). While the underlying TPS61070DDC IC supports adjustable output via external feedback, this specific EVM variant does not include provisions for voltage adjustment. Users requiring variable output must modify the feedback network or select a different evaluation platform.

What are the key safety warnings associated with operating the TPS61070EVM-062?

TI specifies strict operational limits for the TPS61070EVM-062: input voltage must remain within 0.9 V–5.5 V (absolute max 6 V), and loads must stay within the 300-mA output rating. Exceeding these ranges risks irreversible damage. Additionally, certain components - including the inductor and switching transistor - may exceed 125°C case temperature during normal operation, requiring careful thermal handling and probe placement.

Which components on the TPS61070EVM-062 board are critical for maintaining its specified 5-V output accuracy?

The output voltage accuracy on the TPS61070EVM-062 depends primarily on the external feedback resistors R1 (909 kΩ) and R2 (100 kΩ), which set the 5-V regulation point per the TPS61070DDC's 0.6-V internal reference. Their 1% tolerance directly impacts output tolerance. The TDK C2012X5R0J106KT (10 µF/6.3 V) input capacitor also plays a critical role in stabilizing input ripple and supporting transient response.

Is the TPS61070EVM-062 compliant with FCC or CE electromagnetic compatibility standards?

No - the TPS61070EVM-062 is explicitly designated for engineering development and evaluation only. As stated in TI's EVM Important Notice, it is not regulatory-compliant or agency-certified (FCC, UL, CE, etc.) due to its open construction and lack of shielding or filtering required for commercial EMC compliance. It is intended for lab use only and must not be deployed in end products without additional system-level certification.
