The PT6603B is a non-isolated point-of-load (PoL) DC DC converter module from Texas Instruments, part of the PT6600 series. It delivers a regulated 2.5V output from a 4.5V to 6.0V input bus (3.1V to 6.0V for outputs ≤1.8V). The output current is rated at 9A with 200 LFM airflow at 60°C, or 7A in natural convection at 25°C. Maximum power is 18W.
Typical efficiency is 76% at 8A load and 85% at 3A load. The switching frequency is 600kHz typical. Line regulation is ±7mV typical (±13mV max), and load regulation is ±13mV typical (±25mV max). Output ripple and noise is 50mVpp. Transient response shows 100µs settling time with 150mV overshoot/undershoot for a 4A to 8A step. The output voltage is adjustable from 1.80V to 3.50V via pin 14.
Features include remote on/off, over-temperature protection, remote sense, and standby function. Note that the module does not include short circuit protection. It requires two external 330µF electrolytic capacitors (C1 and C2) for proper operation.
The PT6603B is housed in a 14-SMD surface mount module with dimensions 59.9mm x 31.0mm x 10.7mm. Operating temperature range is -40°C to 85°C. It is intended for commercial ITE (Information Technology Equipment) applications.
