Design a Custom BoardAbout This Component
High-performance fixed-frequency current mode PWM controller for offline and DC-DC converter applications. Features 250 kHz oscillator, integrated error amplifier, cycle-by-cycle current limiting, and high-current totem pole output for direct MOSFET drive. Includes input and reference undervoltage lockout with hysteresis, programmable deadtime, and single-pulse metering latch for robust power supply design.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
