Design a Custom BoardAbout This Component
This fixed-frequency current-mode PWM controller IC implements isolated flyback, boost, and DC-DC converter topologies with minimal external components. Operating up to 500 kHz, it features a precision-trimmed oscillator, a high-current totem-pole output for direct N-channel MOSFET drive, and latching cycle-by-cycle current limiting. The device incorporates a 16V/10V undervoltage lockout threshold and draws under 0.5 mA during startup, targeting off-line AC/DC power supplies and isolated DC converters.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
The 1.27mm pitch and surface-mount pads on this eight-pin package are difficult to hand-solder reliably and incompatible with standard breadboards. A breakout board lets you prototype with through-hole connectors and larger pads, dramatically reducing assembly frustration while maintaining electrical integrity for sensitive analog and switching applications.
