Description
The A8582 is an adjustable frequency, high output current,
PWM regulator that integrates a low resistance, high-side,
N-channel MOSFET. The A8582 incorporates current-mode
control to provide simple compensation, excellent loop
stability, and fast transient response. The A8582 utilizes
external compensation to accommodate a wide range of power
components to optimize transient response without sacrificing
stability.
The A8582 regulates input voltages from 4.7 to 36 V, down to
output voltages as low as 0.8 V, and is able to supply at least
2.0 A of load current. The A8582 features include an externally
adjustable switching frequency, an externally set soft start
time to minimize inrush currents, an EN/SYNC input to either
enable VOUT and/or synchronize the PWM switching
frequency, and a Power OK (POK) output to indicate when
VOUT is within regulation. The A8582 only turns on the
lower FET to charge the boot capacitor when needed, not at
