Table 1 provides a summary of the TPS63036EVM-163 performance specifications. All specifications are

given for an ambient temperature of 25°C.

Table 1. Performance Specification Summary

Specification Test Conditions Min Typ Max Unit

Input voltage 1.8 5.5 V

Output voltage Vin = 4.2 V, Iout = 500 mA 3.2 3.3 3.4 V

Output current Vin = 3.6 V 0 600 mA

Operating frequency 2000 kHz

1.3 Modifications

The printed-circuit board (PCB) for this EVM is designed to accommodate both the fixed and adjustable

versions of this integrated circuit (IC). If the fixed version is installed, R1 is replaced with a 0-Ω resistor

and R2 is open.

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 5.5-V. See the TPS63036 data sheet

(SLVSB76) for recommended values.

1.3.2 Fixed Output Operation

U1 can be replaced with the fixed version for evaluation. R1 must be replaced with a 0-Ω resistor; the R2

position is open.

2 Setup and Results

This section describes how to properly use the TPS63036EVM-163.

2.1 Input / Output Connector and Header Descriptions

2.1.1 J1 – VIN

This header is the positive connection to the input power supply. The power supply must be connected

between J1 and J3 (GND). The leads to the input supply should be twisted and kept as short as possible.

The input voltage has to be between 1.8-V and 5.5-V.

2.1.2 J2 – VIN Sense/GND Sense

Header J2 can be used to measure the input voltage directly on the input capacitor. Therefore a 4-wire

power & sense supply can be connected. The leads to the sensing connector should also be twisted.

2.1.3 J3 – GND

This header is the return connection to the input power supply. Connect the power supply between J3 and

J1 (VIN). The leads to the input supply should be twisted and kept as short as possible. The input voltage

has to be between 1.8-V and 5.5-V.

2.1.4 J4 – VOUT

This header is the positive connection of the output voltage. The load has to be connected between J4

and J6 (GND).
