The Texas Instruments LM43603PWPR is a high-performance synchronous step-down (buck) voltage converter designed for a wide input voltage range of 3.5V to 36V. It can deliver a maximum output current of 3A.
Key electrical specifications include a low quiescent current of 27 µA, enabling high efficiency at light loads. The output voltage can be adjusted from 1V to 28V. The device features an adjustable switching frequency ranging from 200 kHz to 2.2 MHz, with a default of 500 kHz, and supports frequency synchronization to an external clock.
This converter offers several integrated features for robust operation, including overcurrent protection, power-good flag, soft start, and thermal shutdown protection. It is designed to be stable with various capacitor types and meets EN55022/CISPR 22 EMI standards.
The LM43603PWPR is available in HTSSOP (PWP) 16 and VSON (DSU) 16 packages, measuring 32 mm² (5 mm × 6.4 mm) and 20 mm² (5 mm × 4 mm) respectively. The operating temperature range is -40°C to 125°C.
