PRODUCT 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.

The ADP1850 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.

The accurate current limit (±6%) allows the power architect to design within a narrower range of tolerances and can reduce overall converter size and cost. The ADP1850 provides a configurable architecture capable of wide range input operation to provide the designer with maximum re-use opportunities and improved time to market.

Additional flexibility is provided by external programmability of loop compensation, soft start, frequency setting, power saving mode, current limit and current sense gain can all be programmed using external components. The ADP1850 includes a high level of integration in a small size package.

The start-up linear regulator and the boot-strap diode for the high side drive are included. Protection features include: undervoltage lock-out, overvoltage, overcurrent/short-circuit and over temperature. The ADP1850 is available in a compact 32-lead LFCSP 5 mm × 5 mm thermally enhanced package.
