The converters operate in forced continuous or pulse skip mode for low noise or in Burst Mode® operation for high efficiency at light loads. The common buck switching frequency is 2MHz and can be synchronized to an external oscillator via the MODE/SYNC pin. The converters can regulate outputs as low as 500mV. Features include precision enable thresholds, a PGOOD signal, output overvoltage protection, and thermal shutdown. They also include output short-circuit protection and up to 100% duty cycle operation for low dropout.
