TPIC74100EVM の特徴
- 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
TPIC74100EVM に関する概要
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.
