ADP1850 Datasheet (Analog Devices) - DC-to-DC Synchronous Buck Controller

ADP1850, DC-to-DC Synchronous Buck Controller

The ADP1850 is a configurable dual output or two-phase, single output dc-to-dc synchronous buck controller capable of running from commonly used 3.3 V to 12 V (up to 20 V) voltage inputs.

The device operates in current mode for improved transient response and uses valley current sensing for enhanced
