XR77128：Quad Channel Digital Programmable Power Management System with Selectable DrMOS Output
The XR77129 is a quad channel Digital Pulse Width Modulated (DPWM) step down (buck) controller. An extremely wide 6V to 40V input voltage range allows for single supply operation from standard power rails.
With integrated FET gate drivers, two LDOs for standby power and a 105kHz to 1.23MHz independent channel to channel programmable constant operating frequency, the XR77129 reduces overall component count and solution footprint and optimizes conversion efficiencies. A selectable digital Pulse Frequency Mode (DPFM) capable of better than 80% efficiency at light current load and low operating current allow for portable and Energy Star compliant applications. Each XR77129 output channel is individually programmable as low as 0.6V with a resolution as fine as 2.5mV, and configurable for precise soft start and soft stop sequencing, including delay and ramp control.
The XR77129 operation is fully controlled via a SMBus-compliant I2C interface allowing for advanced local and/or remote reconfiguration, full performance monitoring and reporting as well as fault handling.
Built-in independent output Over-Voltage, Over-Temperature, Over-Current and Under-Voltage Lockout protections insure safe operation under abnormal operating conditions.
The XR77129 is offered in a RoHS compliant, "green"/halogen free 44-pin TQFN package.
