Demonstration circuit 2523A is an 18V, 8.5A (continuous)/12A (peak) synchronous step-down Silent Switcher® with 16µA quiescent current featuring the LT8652S. The LT8652S is a compact, high efficiency, high speed synchronous monolithic step-down switching with the second generation Silent Switcher structure that minimizes EMI and reduces PCB layout sensitivity. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8652S to minimize external components and simplify design. The demo board has two outputs: 3.3V and 1.2V from a 3.6V to 18V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The SYNC pin on the demo board is grounded by default for low ripple Burst Mode® operation. Move JP2 to FCM without SSM position can change the operation mode to forced continuous mode operation. Once JP2 is on FCM with SSM position, VCC is applied to the SYNC pin for low EMI spread spectrum operation. To synchronous to an external clock, move JP2 to SYNC and apply the external clock to the SYNC turret. The demonstration circuit 2523A runs at 2MHz to minimize solution size. The peak efficiency is 90%. The IC temperature rise is less than 70°C when both channels run at full load, 8.5A each, at 2MHz. The demo board has EMI filters installed for both channels. To use the EMI filter, the input should be tied to VEMI1/VEMI2, not VIN1/VIN2. The LT8652S data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this demo manual for DC2523A.

The LTC3226 is a 2-cell series supercapacitor charger with a backup PowerPath controller. It includes a charge pump supercapacitor charger with programmable output voltage, a low dropout regulator, and a power-fail comparator for switching between normal and backup modes.The constant input current supercapacitor charger is designed to charge two supercapacitors in series to a resistor-programmable output voltage from a 2.5V to 5.3V input supply. The charger input current limit is programmable by an external resistor at up to 315mA.The internal backup LDO is powered from the supercapacitors and provides up to 2A peak output current with an adjustable output voltage. When the input supply falls below the power-fail threshold, the LTC3226 automatically enters a backup state in which the supercapacitors power the output through the LDO. The input supply power-fail voltage level is programmed by an external resistor divider.Low input noise, low quiescent current and a compact footprint make the LTC3226 ideally suited for small, batterypowered applications. Internal current limit and thermal shutdown circuitry allow the device to survive a continuous short-circuit from the PROG or CPO pins to ground.Applications Smart Power Meters Battery-Powered Industrial/Medical Equipment 3.3V Solid-State Drives Industrial Alarms Data Backup Supplies Battery Hold-Up Supplies

The DC2810A default input voltage range is 4.5V to 15V. However, if VIN is lower than 4.5V, minor modification to certain existing onboard components is required. Please refer to Step 8: Operation at VIN ≤ 4.5V in Quick Start Procedure section. The factory default output voltages are VOUT0 = 1V, VOUT3 = 0.9V at 12A per channel; VOUT1 = 1.2V, VOUT2 = 1.8V at 5A per channel. The DC2810A output voltages can be adjusted from 0.6V up to 3.3V for channel 0 and channel 3 and from 0.6V to 5.5V for channel 1 and channel 2. The default switching frequencies are 600kHz for channel 0 and channel 3 and 1MHz for channel 1 and channel 2. Forced airflow and heatsink might also be used to further optimize the output power when all output rails are on and fully loaded. Programming the output voltages to values greater than 1.8V, may require derating output current based on thermal derating curves provided in the data sheet of the LTM4673.
