TPS62088YWCEVM-084 Evaluation Module
1 Introduction
The TPS62088YWC is a synchronous, step-down converter in a 1.2- x 0.8- x 0.3-mm wafer chip-scale
package (WCSP).
1.1 Performance Specification
Table 1 provides a summary of the TPS62088YWCEVM-084 performance specifications.
Table 1. Performance Specification Summary
SPECIFICATION MIN TYP MAX UNIT
Input voltage 2.4 5 5.5 V
Output voltage setpoint 1.8 V
Output current 0 3000 mA
1.2 Modifications
The printed-circuit board (PCB) for this EVM is designed to accommodate both the fixed and adjustable
output voltage versions of this integrated circuit. Additional input and output capacitors can also be added.
Finally, the loop response of the device can be measured.
1.2.1 Fixed Output Voltage Operation
U1 can be replaced with the fixed output voltage version of the device for evaluation. For fixed output
voltage version operation, replace R1 with a 0-
Ω
resistor and remove R2 and C4.
1.2.2 Input and Output Capacitors
C9 is provided for an additional input capacitor. This capacitor is not required for proper operation but can
be used to reduce the input voltage ripple.
C6, C7, and C8 are provided for additional output capacitors. These capacitors are not required for proper
operation but can be used to reduce the output voltage ripple and to improve the load transient response.
The total output capacitance must remain within the recommended range in the data sheet for proper
operation.
