Wide Range Input, Dual/Two-Phase, DC-to-DC
Synchronous Buck Controller ADP1850 Data Sheet
FEATURES TYPICAL OPERATION CIRCUIT APPLICATIONS
High current single and dual output intermediate bus and
point of load converters requiring sequencing and
tracking capability, including converters for:
Point-of-load power supplies
Telecom base station and networking
Consumer
Industrial and instrumentation
Healthcare and medical GENERAL DESCRIPTION
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 noise
immunity.
The architecture enables accurate current sharing between
interleaved phases for high current outputs.
The ADP1850 is ideal in system applications requiring multiple
output voltages: the ADP1850 includes a synchronization feature to eliminate beat frequencies between switching devices;
provides accurate tracking capability between supplies and
includes precision enable for simple, robust sequencing. …
