Optimized for consumer applications concerned with audible noise elimination, this solution extends the advantages of transition mode-high efficiency with low-cost components-to higher power ratings than previously possible. By utilizing a Natural Interleaving technique, both channels operate as masters (that is, there is no slave channel) synchronized to the same frequency. This approach delivers inherently strong matching, faster responses, and ensures that each channel operates in transition mode.
Complete system-level protections feature input brownout, output over-voltage, open-loop, overload, soft-start, phase-fail detection, and thermal shutdown. The additional FailSafe over-voltage protection (OVP) feature protects against shorts to an intermediate voltage that, if undetected, could lead to catastrophic device failure.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other condition beyond those included under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods of time may affect device reliability.
(2) Voltage on VCC is internally clamped. VCC may exceed the absolute maximum input voltage if the source is current limited below the absolute maximum continuous VCC input current level.
(3) In normal use, COMP is connected to capacitors and resistors and is internally limited in voltage swing.
(4) In normal use, VINAC, VSENSE, and HVSEN are connected to resistors and are internally limited in voltage swing. Although not recommended for extended use, VINAC, VSENSE, and HVSEN can survive input currents as high as ±10 mA from high voltage sources.
(5) No GDA or GDB current limiting is required when driving a power MOSFET gate. However, a small series resistor may be required to damp ringing due to stray inductance. See Figure 12 and Figure 13 for details.
