Overview
Description
Key features of the TPS54540BDDAR include a maximum output current of 5A, high efficiency (up to 95%), and a switching frequency adjustable from 100 kHz to 2.5 MHz. It also offers enhanced protection features such as overcurrent protection, thermal shutdown, and undervoltage lockout, ensuring reliable operation in various conditions.
The device comes in an 8-pin SO PowerPAD package, facilitating effective heat dissipation. Its compact design and high performance make it ideal for space-constrained environments that require robust power solutions.
Overall, the TPS54540BDDAR is a versatile and efficient power management solution for applications requiring reliable voltage regulation in a compact footprint.
Features
1. Wide Input Voltage Range: Capable of operating with an input voltage from 5.5V to 42V, suitable for various applications including industrial and automotive.
2. Output Current: Supports up to 5A continuous output current, making it ideal for moderate power applications.
3. Efficiency: High efficiency, often exceeding 90% depending on the load and input/output conditions, which reduces heat generation.
4. Adjustable Output Voltage: The output voltage is adjustable from 0.8V to 90% of the input voltage, providing flexibility for different application needs.
5. Switching Frequency: Features a fixed switching frequency of 500 kHz, which aids in reducing the size of external components.
6. Protection Features: Includes built-in protection features such as cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout to ensure robust operation.
7. Package: Offered in a small thermally-enhanced 8-pin SO PowerPAD™ (DDA) package, which aids in efficient heat dissipation.
These features make the TPS54540BDDAR a versatile and reliable choice for point-of-load power supplies in various sectors.
Package
Pinout
1. BOOT: Bootstrap capacitor connection for the high-side FET gate drive.
2. VIN: Input voltage supply pin.
3. EN: Enable pin to turn the device on or off.
4. SS/TR: Soft Start/Tracking pin to control the soft start time or track an external voltage.
5. COMP: Compensation pin for loop compensation.
6. RT/CLK: Frequency set pin, which can also accept an external clock signal for synchronization.
7. PH: Switching (Phase) node output, connected to the inductor.
8. GND: Ground pin.
These pins together allow the TPS54540BDDAR to efficiently convert a higher input voltage to a lower output voltage with adjustable frequency and soft start features.
