Description
This converter provides up to 3 A of continuous output current and is characterized by its low quiescent current, making it highly efficient even at light loads. The device supports a 100% duty cycle for the lowest dropout voltage and features a selectable switching frequency of either 2.5 MHz or 1 MHz to optimize efficiency and size.
The TPS62903RPJR incorporates features like soft start, power-good indicators, and overcurrent protection, enhancing its reliability and robustness. Its small footprint, combined with a minimum number of external components, simplifies the design and reduces the overall solution size, making it ideal for space-constrained applications.
Equivalent
1. LMR33630 from Texas Instruments
2. MPM3680 from Monolithic Power Systems
3. LTC3603 from Analog Devices
4. AP63300 from Diodes Incorporated
It's important to compare specific parameters like efficiency, package type, and additional features when selecting an equivalent.
Features
This converter offers high efficiency across light and heavy loads, thanks to its low quiescent current (IQ) and DCS-Control™ topology, which ensures fast transient response and low output voltage ripple. The TPS62903RPJR also includes several protection features such as overcurrent protection, thermal shutdown, and undervoltage lockout to ensure reliable operation.
The device operates at a fixed frequency of 2.5 MHz, enabling the use of small inductors and capacitors, which reduces the overall solution size. It comes in a tiny 2 mm x 3 mm QFN package, making it ideal for space-constrained designs.
Pinout
1. VIN: Input voltage supply.
2. EN: Enable pin to turn the device on or off.
