MAX15301
InTune Automatically Compensated Digital PoL
Controller with Driver and PMBus Telemetry
General Description
Features
The MAX15301 is a full-featured, highly efficient, digital
point-of-load (PoL) controller with advanced power man-
agement 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 duty-
cycle saturation effects. These capabilities result in fast
loop transient response and reduce the number of output
capacitors compared to competing digital controllers.

S PMBus Interface for Configuration, Control, and
Monitoring
The MAX15301 includes multiple features to optimize
efficiency. An internal switch BabyBuck™ regulator gen-
erates 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.

Variable Gate-Drive Voltage
S Wide Input Range of 4.5V to ±4V
S Efficient On-Chip BabyBuck Regulator for Self-
Bias
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 monitor-
ing ICs. Basic DC-DC conversion operation can be set
up via pin strapping and does not require user configu-
ration 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.
