Texas Instruments TPS61100EVM-216

Overview

TPS61100EVM-216 from Texas Instruments is an evaluation module designed to demonstrate the dual-output, single-cell boost converter TPS61100. It supports input voltages from 0.8 V to 3.3 V, delivers up to 5.5 V from its adjustable boost stage and a second regulated output via integrated 120 mA LDO, and enables rapid validation of battery-powered portable systems including PDAs, digital cameras, and internet audio players.

For engineers reviewing the TPS61100EVM-216 datasheet, TPS61100EVM-216 setup guide, TPS61100EVM-216 test configuration, or TPS61100EVM-216 compatibility with TPS61100/TPS61103/TPS61106/TPS61107 ICs, this module provides verified reference schematics, layout files, BOM, and functional test points for both boost and LDO outputs under real-world load and shutdown conditions.

Technical Context

The TPS61100EVM-216 implements the full feature set of the TPS61100 IC: synchronous PWM boost topology operating at 320–800 kHz, integrated antiringing switch for low EMI, auto-discharge function (400 Ω internal switch), and independent enable/control logic for boost (EN/ENPB) and LDO (LDOEN) stages. It supports dual power rail generation from a single-cell NiCd/NiMH or alkaline source down to 0.8 V.

Board-level design includes validated external components: 10 µH boost inductor (SUMIDA CDRH74–100), 10 µF ceramic input capacitor, 100 µF low-ESR tantalum output capacitor, and 2.2 µF LDO output capacitor. All control signals - SKIPEN, ADEN, LBI, PGOOD, LBO1/LBO2 - are accessible via test points or headers for system integration testing.

FAQ

What is the primary purpose of the TPS61100EVM-216?

The TPS61100EVM-216 is an evaluation module that demonstrates the complete functionality of the TPS61100 dual-output boost converter IC. It allows engineers to validate performance metrics - including efficiency, startup behavior, load transient response, auto-discharge timing, and LDO regulation - using production-grade circuitry and documented test procedures before committing to custom PCB design.

Which IC variants does the TPS61100EVM-216 support?

The TPS61100EVM-216 is optimized for the TPS61100 but fully supports functional evaluation of TPS61103 (3.3 V boost + adjustable LDO), TPS61106 (3.3 V boost + 1.5 V LDO), and TPS61107 (3.3 V boost + 1.8 V LDO). Pin-compatible placement and identical control interface ensure seamless substitution across the TPS6110x family without board modification.

Does the TPS61100EVM-216 include layout files and BOM?

Yes - the TPS61100EVM-216 includes complete design resources: Gerber files, schematic PDF, bill of materials (BOM) with Digi-Key/Mouser part numbers, assembly drawing, and test report. These are provided by Texas Instruments and hosted on ti.com under SLVS411B documentation package.

How is low-battery monitoring implemented on the TPS61100EVM-216?

The TPS61100EVM-216 implements programmable low-battery detection using the LBI input and dual LBO1/LBO2 open-drain outputs. Thresholds (400 mV, 450 mV, 500 mV) are set via external resistive divider on LBI; corresponding status flags appear on LBO1/LBO2 per documented truth table. Pull-up resistors (1 MΩ recommended) are included on-board.

Can the TPS61100EVM-216 be used to evaluate power save mode and auto-discharge behavior?

Yes - the TPS61100EVM-216 provides direct access to SKIPEN and ADEN pins via jumpers or test points, enabling controlled activation of power save mode and auto-discharge function. Output capacitor discharge time can be measured at VOUT and LDOOUT using oscilloscope probes, validating system-level shutdown sequencing requirements.
