2 Description

The TPSM8A29EVM is configured for operation with a 4-V to 16-V input voltage. A wide range of output voltages (0.8 V to 5 V) can be configured using the included header (see Section 3.5). Three different switching frequencies (600 kHz, 800 kHz, 1 MHz), as well as forced-continuous conduction mode (FCCM) or discontinuous conduction mode (DCM) operation are also configured using the included header (see Section 3.4). Any output voltage from 0.6 V to 5.5 V can be set by using Equation 3 and Equation 4.

Several test points are included to facilitate the measurement and evaluation of device performance. Several other test points can be used to monitor control signals, or to use as external input control signals to the TPSM8A29. See Section 4 for a detailed description of the TPSM8A29EVM test points.

The wide input voltage range, output voltage range, high current output, small solutions size, and flexible operating modes of the TPSM8A29 make the TPSM8A29 an excellent choice for a wide range of markets.
