SCT81620Q Wide Vin 50V Non-synchronous Boost/Flyback/SEPIC Controller
●The SCT81620Q device is a wide input, non- synchronous boost controller. The Device can be used in Boost, SEPIC and Flyback converters and topologies.
●The switching frequency of the SCT81620Q device can be adjusted to any value between 100kHz and 2.2MHz by using a single external resistor or by synchronizing it to an external clock. Current mode control provides superior bandwidth and transient response in addition to cycle-by-cycle current limiting. Current limit is adjustable through an external resistor.
●The SCT81620Q is an Electromagnetic Interference (EMI) friendly controller with implementing optimized design for EMI reduction. The SCT81620Q features Frequency Spread Spectrum (FSS) with ±6% jittering span of the switching frequency and modulation rate 1/512 of switching frequency to reduce the conducted EMI.
●The SCT81620Q device has built-in protection features such as thermal shutdown, short-circuit protection and overvoltage protection. Power-saving shutdown mode reduces the total supply current to 3.7 μA. Integrated current slope compensation simplifies the design and, if needed for specific applications, can be increased using a single resistor.
●The device is available in a MSOP-8L(3mm*3mm) Package.
