SQ35702E is a fixed frequency and current mode controller for Boost/ Flyback/Sepic topology. UVLO and OTP protection are available to protect IC. Cycle by cycle current limit (1V) and over current limit (1.1V) for ISEN.Typical 170uA starting up current and 1.5mA operating supply current exclude MOS driving current. Flexible frequency and minimum off time set by FS pin and up to 250 kHz switching frequency. Up to 1A GATE sourcing and sinking capability for driving large external MOSFET.SQ35702E is available in a SO8 package.
