Product Overview
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.
- Wide range input is 2.75V to 20V, synchronization input
- Power stage input voltage is 1V to 20V, thermal overload protection
- Output voltage range is 0.6V upto 90% VIN, quiescent current is 4.5mA typ
- Output current to more than 25A per channel, input undervoltage lockout (UVLO)
- Accurate current sharing between channels (interleaved)
- 180° phase shift between channels for reduced input capacitance
- Integrated boost diodes, power saving mode (PSM) at light loads
- Accurate power good with internal pull-up resistor, accurate voltage tracking capability
- Independent channel precision enable, overvoltage and overcurrent limit protection
- Operating temperature is -40°C to +85°C, package style is 32-lead LFCSP
