The PJ16606 is a 6A non-synchronous stepdown DC-DC converter operating over a wide input voltage range of 5.8V to 60V and providing a regulated low output voltage. It integrates a 80mΩ high-side MOSFET for highefficiency power conversion. The device utilizes peak current mode control with Pulse- Skipping Modulation (PSM) to maintain high efficiency under light-load and standby conditions.
The switching frequency can be adjusted from 200 kHz to 2.2 MHz by setting an external resistor, allowing the system to be optimized for either high efficiency or a compact component footprint. The converter efficiently steps down a high input voltage to a low output voltage while supporting a minimum high-side MOSFET on-time of 50ns.
A fixed 4ms soft-start time limits inrush current during output voltage startup, and the device supports monotonic startup with a prebiased output. Comprehensive protection features include cycle-by-cycle current limit, hiccup-mode over current protection, thermal shutdown, output over voltage protection, and input under voltage protection.
