36V, 3.5A(IOUT), 2.4MHz Step-Down DC/DC Converter Draws Quiescent Current of Only 75uA
The LT3680 utilizes a high efficiency 4.6A, 95mOhm switch, with the necessary boost diode, oscillator, control and logic circuitry integrated into a single chip. Low ripple Burst Mode operation maintains high efficiency at low output currents while keeping output ripple below 15mVPK-PK. Special design techniques used in the LT3680 enable high efficiency over a wide input voltage range, and the devices’s current mode topology enables fast transient response and excellent loop stability. Other features include external synchronization (from 250kHz to 2MHz), a power good flag and soft-start capability.
Pricing for the LT3680EDD and LT3680EMSE starts at $4.15 and $4.25 each, respectively for 1,000-piece quantities. The LT3680IDD and LT3680IMSE are tested and guaranteed to operate from a -40°C to 125°C operating junction temperature. All versions are available from stock.
