The LTC1779 boasts a 2.5% output voltage accuracy and consumes only 135A of quiescent current. For applications where efficiency is a prime consideration, the LTC1779 is configured for Burst Mode operation, which enhances efficiency at low output current. To further maximize the life of a battery source, the internal P-channel MOSFET is turned on continuously in dropout (100% duty cycle). In shutdown, the device draws a mere 8A. High constant operating frequency of 550kHz allows the use of a small external inductor.
