DC1992A

DC1992A is a LT8620 65V, 2A micropower synchronous monolithic step-down regulator demonstration board. Demonstration circuit 1992A is a 65V, 2A micropower synchronous monolithic step-down regulator featuring the LT®8620. The LT8620 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 2.5µA of quiescent current when output is regulated at 5V. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8620 to minimize external components and simplify design. The SYNC pin on the demo board is grounded by default for low ripple Burst Mode® operation. The demo board has an EMI filter installed. The board and the IC are designed to minimize conducted and radiated EMI.

• Switching frequency of 2MHz(typ) at TA = 25°C
• Efficiency of 92% at TA = 25°C, IOUT1 = 1A
