DC converter with a ripple simulation, 4A switch operating from a 2. With a unique single feedback pin architecture it is capable of boost, SEPIC or inverting configurations.
Burst Mode operation consumes as low as 9μA quiescent current to maintain high efficiency at very low output currents, while keeping typical output ripple below 15mV. MODE pin allows synchronization to an external clock. It can also be used to select between burst or pulse-skip modes of operation with or without Spread Spectrum Frequency Modulation for low EMI. For increased efficiency, a BIAS pin can accept a second input to supply the INTVCC regulator.
3mm DFN package or a thermally enhanced 16-lead MSOP package with four pins removed. The product is appropriate for new designs but newer alternatives may exist. Demo circuit 2716A features the LT8364 in boost configuration. It is designed to convert a 4. 5V to 20V source to 24V, with up to 1. 6A, depending on input voltage, with a switching frequency of 2MHz. The LT8364 can operate with inputs as high as 60V, however, in this demo circuit, the input is limited by the level of the output voltage.
