Description
The A8650 is an adjustable frequency, high output current,
PWMregulatorthatintegratesahigh-side,P-channelMOSFET
and a low-side, N-channel MOSFET. TheA8650 incorporates
current-modecontroltoprovidesimplecompensation,excellent
loop stability, and fast transient response. The A8650 utilizes
external compensation to accommodate a wide range of power
components to optimize transient response without sacrificing
stability. TheA8650 regulates input voltages from 2.5 to 5.5 V,
down to output voltages as low as 0.8 V, and is able to supply
at least 2.0 A of load current.
A8650 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
sleep mode current of the A8650 control circuitry is less than
3 μA. Protection features include VIN undervoltage lockout
A8650-DS, Rev. 8
