These three devices differ in their light load behavior. The TPS564252 operates in Eco-mode, the TPS564255 operates in OOA mode, and the TPS564257 operates in FCCM mode. This user's guide contains information for the TPS564252, TPS564255, and TPS564257 as well as support documentation for the TPS564252EVM, TPS564255EVM, and TPS564257EVM evaluation modules. This document also includes the performance specifications, board layout, schematic, and the list of materials of the TPS564252EVM, TPS564255EVM, and TPS564257EVM. • • • • Performance specifications Board layout Schematic List of materials 1.1 Introduction In light-load conditions, the TPS564252 operates in Eco-mode to enable higher efficiency by varying the switching frequency, the TPS564257 operates in FCCM to maintain constant switching frequency and the TPS564255 operates in OOA mode to avoid audio noise. The main difference is at light loading, but the other behaviors are similar. This user's guide mainly introduces the TPS564252 and includes some TPS564257 and TPS564255 features that are different from the TPS564252. The TPS56425x is a single, adaptive on-time, D-CAP3™ control mode, synchronous buck converter that requires a very low external component count. The D-CAP3 control mode circuit is optimized for low-ESR output capacitors such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no external compensation. The switching frequency is internally set at a nominal 600 KHz. The high-side and low-side switching MOSFETs are incorporated inside the TPS56425x package along with the gate-drive circuitry. The low drain-to-source on resistance of the MOSFETs and fast switching slew rate allow the TPS56425x to achieve high efficiency and help keep the junction temperature low at high output currents. Power sequencing is possible by correctly configuring the enable and power-good indicator. The TPS56425x DC/DC synchronous converter is designed to support up to a 4-A continuous current from an input voltage source of 3 V to 17 V. The output voltage range is from 0.6 V to 10 V. Rated input voltage and output current ranges for the evaluation module are given in Table 1-1. The TPS564252EVM evaluation module (EVM) is a single, synchronous buck converter providing 1.05 V at 4 A from 3-V to 17-V input. This user’s guide describes the TPS564252EVM performance. Table 1-1.

The EVM also includes AC signal injection terminals for feedback loop measurements. Specification, application information, and schematic are shown in Section 4 and Section 5.1. 1.4 Device Information Synchronous buck converter TPS56425X is used in the EVM to achieve the high-efficiency power delivery and voltage conversion. The TPS564252 operates in Eco-mode, which maintains high efficiency during light loading. The TPS564257 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. The TPS564255 operates in OOA mode, which prevents audio noise generation. 2 Step-Down Converter Evaluation Module SLUUCL5A – DECEMBER 2022 – REVISED MAY 2023 Submit Document Feedback Copyright © 2023 Texas Instruments Incorporated www.ti.com Evaluation Module Overview Device Information PART NUMBER Mode TPS564252 ECO TPS564255 OOA TPS564257 FCCM SLUUCL5A – DECEMBER 2022 – REVISED MAY 2023 Submit Document Feedback Package DRL (SOT-563, 6) Step-Down Converter Evaluation Module Copyright © 2023 Texas Instruments Incorporated 3 Performance Specification Summary www.ti.com 2 Performance Specification Summary A summary of the TPS564252EVM performance specifications is provided in Table 2-1. Specifications are given for an input voltage of VIN = 12 V and an output voltage of 1.05 V, unless otherwise noted. The ambient temperature is 25°C for all measurement, unless otherwise noted. Table 2-1. Performance Specifications Summary SPECIFICATIONS TEST CONDITIONS Input voltage range MIN TYP MAX 3 12 17 Output voltage set point Operating frequency VIN = 12 V, IO = 2 A Output current range VIN = 12 V, LO = 1.5 µH Output ripple voltage VIN = 12 V, IO = 4 A V 1.05 V 600 KHz 0 Over current limit UNIT 4 A 5.6 A 11 mVPP 3 Output Voltage Setpoint The output voltage of the EVM can be selected by changing the value of resistor R4 (RUPPER) and R5 (RLOWER). The value of R4 for a specific output voltage can be calculated using Equation 1. The output voltage is set with a resistor divider from the output node to the FB pin. TI recommends using 1% tolerance or better divider resistors. Start with a 10 kΩ or 30 kΩ for R4 (RFBB) and use Equation 1 to calculate R5 (RFBT) . To improve efficiency at light loads, consider using larger value resistors. If the values are too high, the regulator is more susceptible to noise and voltage errors from the FB input current are noticeable.
