Figure 14–5. Asynchronous Switching Regulator
Synchronous switching regulators have a voltage- or current-controlled
oscillator that controls the on and off time of the two MOSFET devices
that supply the current to the circuit (see
Figure 14–6. Voltage-Controlled Synchronous Switching Regulator
Maximum Output Current
Select an external MOSFET switching transistor (optional) based on the
maximum output current that it can supply. Use a MOSFET with a low
on-resistance and a voltage rating high enough to avoid avalanche
breakdown. For gate-drive voltages less than 9-V, use a logic-level
MOSFET. A logic-level MOSFET is only required for topologies with a
controller IC and an external MOSFET.
