DC2317A

Demonstration circuit 2317A is a 100V monolithic DC/DC step-down regulator featuring the LTC®7103. The demo board is designed for a 5V/2.3A output from a 5V to 100V input at 400KHz switching frequency. The wide input range makes it suitable for automotive, industrial, medical instrument and telecom applications. This buck regulator has a peak efficiency of 93.5% at 12VIN, 88.3% at 48VIN and 81.5% at 100VIN. The LTC7103 is a compact, high efficiency synchronous monolithic step-down switching regulator with fast current programming. User selectable mode selection (JP1) is provided and Burst Mode® operation position is selected by default. Burst Mode operation increases light load efficiency while pulse-skipping mode allows constant-frequency operation to a lighter load. Board allows phase-locked loop (PLL) synchronization to an external clock by selecting SYNC mode on JP1 and by providing a clock signal on CLKIN turret.

• Approximate size is 25.4mm × 17.78mm × 7.62mm (component area x top component height)
• Demo board has an EMI filter installed
• Provides current monitor and output clock signal to interface with an external application circuit
