Demonstration circuit 1700A is a fast, high efficiency synchronous buck DC/DC converter with 4.5V to 24V input range. It can supply 15A maximum load current at 1.5V output. The demo board features the LTC®3613EWKH regulator. No external MOSFETs are required.
The controlled on-time constant frequency valley current mode architecture allows for both fast transient response and constant frequency switching in steady-state operation.
