    Products Detail

    The PT5820 series provides a full 16A of output current in a low-profile, 18-pin package. The integral copper case construction requires no heatsink and offers solderability and a small footprint (0.736 in² for suffix 'N'). They operate from a 12-V input bus and provide a point-of-load power source for high-performance DSPs and microprocessors. Output voltage options range from 1.0V to 5.0V. Features include external output voltage adjustment (±10%), ±5% margin control, on/off enable, short circuit protection, and thermal shutdown. Both through-hole and surface mount configurations are available.
