ADP1850ACPZ-R7

ADP1850 is a configurable dual output or two-phase, single output dc-to-dc synchronous buck controller. This 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. It provides high speed, high peak current drive capability with dead-time optimization to enable energy efficient power conversion. For low load operation, the device can be configured to operate in power saving mode (PSM) by skipping pulses and reducing switching losses to improve the energy efficiency at light load and standby conditions. It is used in application like 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.
