Beschreibung

The MAX15301AA02 is a full-featured, highly efficient, digital point-of-load (PoL) controller with advanced power management and telemetry features. Unlike PID-baseddigital power regulators, the MAX15301AA02 uses Maxim’s patented InTune™ automatically compensated, state-space control algorithm. The InTune control law is valid for both the small- and large-signal response and accounts for duty-cycle saturation effects. Thesecapabilities result in fast loop transient response and reduce the number of output capacitors compared to competingdigital controllers.The MAX15301AA02 includes multiple features to optimize efficiency. An internal switch BabyBuck™ regulator generates the gate drive and the internal bias supplies for the controller with low power loss.An advanced, high-efficiency MOSFET gate driver has adjustable nonoverlap timing and load-variable gate-drive voltage to minimize switching losses over the full range ofvoltage, current, and temperature.The MAX15301AA02 was designed for end-customer’s design environment. An on-board PMBus™-compliant serial bus interface enables communication with a supervisorycontroller for monitoring and fault management. A full suite of power management features eliminates theneed for complicated and expensive sequencing and monitoring ICs. Basic DC-DC conversion operation can be set up via pin strapping and does not require userconfiguration firmware. This allows for rapid development of the power-supply subsystem before board level systems engineering is completed. Maxim provides support hardware and software for configuring the IC.The MAX15301AA02 is available in a 32-lead, 5mm x 5mm TQFN package and operates over the -40°C to +85°C temperature range.
