Texas Instruments TPS62968EVM Evaluation Module
Texas Instruments TPS62968EVM Evaluation Module is designed to evaluate the TPS62968, TPS62966, and TPS62964 buck converters. The SR142 uses the 8A TPS62968 to output a 0.6V output voltage from input voltages between 3V and 17V. Due to extremely low noise, the TPS62968 is a high-efficiency option for low-dropout (LDO) linear regulators in noise-sensitive circuits.
The TI TPS62968EVM switching frequency is set to 500kHz by default but can be easily adjusted to 700kHz, 1.1MHz, or a synchronized clock.
Features
- Low output 1/f noise < 30μVRMS (100Hz to (100kHz)
