TPS62902RPJR 2A Buck Switching Regulator IC
The TPS62902RPJR is a high-efficiency, 2A synchronous step-down (buck) DC/DC converter from Texas Instruments, designed for space-constrained, power-sensitive applications. This compact converter operates over a wide input voltage range of 3V to 17V, making it suitable for systems powered by 5V, 12V, or battery sources (such as Li-ion or multi-cell configurations). With its ultra-low quiescent current (15µA in PFM mode) and high switching frequency (2.25MHz), the TPS62902RPJR delivers exceptional power efficiency (up to 95%) while minimizing external component size, ideal for IoT devices, portable electronics, and embedded systems. The device features adjustable output voltage (0.6V to 12V) via an external resistor divider, providing flexibility for various load requirements. Its synchronous rectification and forced PWM (Pulse-Width Modulation) mode ensure stable operation under varying load conditions, while optional Power Save Mode (PSM) enhances efficiency at light loads.
For applications requiring different specifications, alternative buck converters include:
● TPS62827 (3A, 17V input, ultra-low IQ for always-on systems)
● LM3671 (2A, 5.5V input, tiny 1.6mm × 0.9mm package for wearables)
● LTC3623 (2.5A, 18V input, high efficiency with external sync capability)
● AP63205 (2A, 18V input, cost-optimized for consumer electronics)
