Features for the TPIC74100EVM
- Switch-Mode Regulator With Integrated Switches
- Less board space
- Lower cost
- Higher EMI performance
- Improved protection off the integrated switches
- Buck/Boost Mode
- Wide input voltage range (ideal for automotive applications where the power supply must stay stable during the start of the engine-cranking pulse)
- Low-Power Operation Mode
- Conserves battery power during conditions with low load current
- Second Output Voltage With Enable Function
- The primary/permanent output voltage can be switched to a second pin, which acts as a second output voltage with enable function.
- Soft-start for second output voltage implemented
- Conserve battery power by disabling second output voltage under certain conditions
- VOUT voltage is protected from failures of the 5Vg line
- Device Enable Function
- Conserve battery power during system shutdown by disabling the device
- Enhanced EMI Performance
- Programmable frequency modulation – spread spectrum
- Programmable slew rate
- Supervision Functionality
- Supervision of input voltage, programmable under-voltage detection threshold, and open-drain output for generation of alarm signal
- Supervision of output voltage, programmable delay timer, and open-drain output for generation of reset signal, e.g., for supervisor microcontroller
- Current Limit
- Protection in case of overcurrent and short-circuit conditions
- Thermal Shutdown
- Protection in case of overtemperature conditions
Description for the TPIC74100EVM
The Texas Instruments TPIC74100EVM evaluation module (EVM) helps designers evaluate the operation and performance of the TPIC74100 Switch Mode Power Supply – Buck Regulator. The EVM contains one DC/DC converter.
