Product Details

Please see Order Tab for recommended replacement devices.

The MAX15301 is a full-featured, highly efficient, digital point-of-load (PoL) controller with advanced power management and telemetry features. Unlike PID-based digital power regulators, the MAX15301 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 dutycycle saturation effects. These capabilities result in fast loop transient response and reduce the number of output capacitors compared to competing digital controllers.
The MAX15301 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 of voltage, current, and temperature.
The MAX15301 was designed for end-customer’s design environment. An on-board PMBus-compliant serial bus interface enables communication with a supervisory controller for monitoring and fault management. A full suite of power management features eliminates the need for complicated and expensive sequencing and monitoring ICs. Basic DC-DC conversion operation can be set up via pin strapping and does not require user configuration 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 MAX15301.
The MAX15301 is available in a 32-lead, 5mm x 5mm TQFN package and operates over the -40°C to +85°C temperature range.
