Texas Instruments TPS60200EVM-145

Overview

TPS60200EVM-145 from Texas Instruments is a single-layer evaluation module designed to characterize the TPS60200 regulated charge pump DC/DC converter, supporting input voltages from 1.6 V to 3.6 V and delivering up to 100 mA at 3.3 V output with low ripple. It implements low-battery detection (LBI/LBO) with 2 V trip point and enables external clock synchronization via the EN pin.

For engineers reviewing the TPS60200EVM-145 datasheet, TPS60200EVM-145 pinout, TPS60200EVM-145 application, or TPS60200EVM-145 equivalent, this EVM provides validated layout, bill-of-material traceability, dual-in-line socket interface compatibility, and direct substitution capability for TPS60201/TPS60202/TPS60203 family devices.

Technical Context

The TPS60200EVM-145 implements a push-pull voltage-doubling charge pump topology using four ceramic capacitors (C1–C4), optimized for space-constrained battery-powered systems. Its layout follows TI's reference design guidelines for minimizing parasitic inductance and EMI in switched-capacitor converters.

The board maps critical signals-including IN, OUT, GND, EN, LBI, and LBO-to a 14-pin DIP socket footprint (pins 1, 3, 7, 8, 12–14 used), enabling plug-and-play integration into test fixtures. The LBO open-drain output includes a 1 MΩ pullup to VO, and the EN pin supports both enable/disable control and 400–800 kHz external clock synchronization.

FAQ

What is the primary function of the TPS60200EVM-145?

The TPS60200EVM-145 is an evaluation module built to validate the performance of the TPS60200 regulated charge pump IC. It delivers a stable 3.3 V output from 1.6–3.6 V inputs, supports low-battery detection, and allows functional testing of enable control, external clock synchronization, and capacitor selection effects on ripple and efficiency. The TPS60200EVM-145 itself is not a semiconductor but a fully assembled PCB with documented layout and BOM.

Can the TPS60200EVM-145 be used with other ICs in the TPS6020x family?

Yes, the TPS60200EVM-145 is explicitly designed for cross-family evaluation: it supports TPS60201, TPS60202, and TPS60203 by replacing the IC. For TPS60201 and TPS60203, the LBI resistors may be removed (though not required), and the existing LBO pullup serves as a power-good indicator. All share identical pinout and capacitor requirements, making the TPS60200EVM-145 a unified platform for comparative analysis.

What are the key layout features of the TPS60200EVM-145?

The TPS60200EVM-145 uses a single-layer PCB with all components and traces on the top side, following TI's charge pump layout best practices to minimize loop area and parasitic inductance. Its 17.9 mm × 10.2 mm size conforms to a 14-pin DIP socket footprint, and only pins 1 (LBI), 3 (OUT), 7–8 (GND), 12 (IN), 13 (EN), and 14 (LBO) are routed-ensuring mechanical compatibility without signal redundancy.

How does the low-battery detection circuit work on the TPS60200EVM-145?

The TPS60200EVM-145 implements low-battery detection using R1 (402 kΩ) and R2 (576 kΩ) to form a resistive divider from the input voltage (VI) to the LBI pin, setting a 2 V trip point referenced to the TPS60200's internal 1.18 V comparator threshold. C5 (100 nF) filters noise at LBI to prevent LBO oscillation. The open-drain LBO output includes a 1 MΩ pullup to VO, producing a clean active-low warning signal below the trip voltage.

What power supply conditions are required to operate the TPS60200EVM-145?

The TPS60200EVM-145 requires a DC input between 1.6 V and 3.6 V applied to the IN and GND terminals. Load must be resistive during startup: ≥33 Ω (≤100 mA) for 2–3.6 V input, ≥66 Ω (≤50 mA) for 1.8–2 V, or ≥132 Ω (≤25 mA) for 1.6–1.8 V. The EN pin is internally pulled high via a 1 MΩ resistor, so no external logic is needed for basic operation-making the TPS60200EVM-145 immediately functional upon power application.
