every PWM cycle. This improves light load efficiency and provides
no-load currents as low as 4 mA at 2 MHz. The sleep mode current
of the A8582 control circuitry is less than 3 μ A.
Protection features include VIN undervoltage lockout (UVLO),
pulse-by-pulse overcurrent protection (OCP), hiccup mode short-
circuit protection (HIC), overvoltage protection (OVP), and thermal
shutdown (TSD). In addition, the A8582 provides unique missing

diode (D1) protection, open-circuit, adjacent pin short-circuit,
and short-to-ground protection at every pin to satisfy the most
demanding applications.
The A8582 device is available in a 16-pin TSSOP package with
exposed pad for enhanced thermal dissipation. It is lead (Pb) free,
with 100% matte tin leadframe plating.

beyond those listed in this table may cause permanent damage to the device. The absolute maximum ratings are
stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the Electrical
Characteristics table is not implied. Exposure to absolute-maximum–rated conditions for extended periods may affect device reliability.
2 SW has internal clamp diodes to GND and VIN. Applications that forward bias these diodes should take care not to exceed the IC
package power dissipation limits.
