Both fixed and adjustable output voltage units are available. 1.1 Background The TPS62110EVM-101 uses the TPS62110 adjustable version and is set to 3.3 V output. The EVM operates with full rated performance with an input voltage between 3.6 V and 17 V. 2 TPS62110 Buck Converter Evaluation Module User's Guide Copyright © 2021 Texas Instruments Incorporated SLVU135A – JUNE 2005 – REVISED JUNE 2021 Submit Document Feedback www.ti.com Introduction 1.2 Performance Specification Table 1-1 provides a summary of the TPS62110EVM-101 performance specifications. All specifications are given for an ambient temperature of 25°C. Table 1-1. Performance Specification Summary Specification Test Conditions Input Voltage Output Voltage Min Typ Max 17 V 3.3 3.333 V 1500 mA 3.6 Iout = 10 mA to 1500 mA Output Current 3.267 0 Low Battery Output (LBO) VIN Power Good (PG) VOUT 5.8 6.0 3.25 6.2 Unit V V 1.3 Modifications The PWB for this EVM is designed to accommodate both the fixed and adjustable versions of this IC. If the fixed version is installed, replace R1 with a 0-Ω resistor; R1 and C3 are open. If additional filtering is desired, C5 can be added. 1.3.1 Adjustable Output IC U1 Operation U1 is configured for evaluation of the adjustable output version. This unit is configured for 3.3 V. Resistors R1 and R2 are used to set the output voltage between 1.2 V and 16 V. See the TPS62110 datasheet (SLVS585) for recommended values. The feedforward capacitor C3 may also need to be changed. For more information see the data sheet. 1.3.2 Fixed Output Operation U1 can be replaced with the fixed version for evaluation. For fixed-version operation, replace R1 with a 0-Ω resistor; R2 and C3 positions remain unpopulated.

J3–VOUT Output voltage connection J4–GND Output return connection, common with J2 J5–LBO/PG Low battery output (LBO) pulled up to Vout; low indicates LBI is below its threshold. Power good (PG), low indicates output voltage is less than 98.4% of the normal value. JP1–SYNC PFM/PWM Input for synchronization to external clock signal. High forces low-noise PWM mode, low enables power save PFM/PWM mode. JP2–EN Enable pin, low on the EN turns unit off. 2.2 Setup To operate the EVM, simply connect an input supply to the appropriate pins, and then connect a load to the appropriate pins. Maximum recommended load is 1.5 A or 2.2 Ω. Input supply of 6 V to 17 V is recommended. 4 TPS62110 Buck Converter Evaluation Module User's Guide Copyright © 2021 Texas Instruments Incorporated SLVU135A – JUNE 2005 – REVISED JUNE 2021 Submit Document Feedback www.ti.com Board Layout 3 Board Layout This section provides the TPS62110EVM-101 board layout and illustrations. 3.1 Layout Figure 3-1 shows the board layout for the TPS62110EVM-101 PWB.
