The FSL306LR integrates a Pulse Width Modulation (PWM) controller and SenseFET and is specifically designed for high performance offline Buck, Buck-Boost and Non-Discrete Flyback Switch Mode Power Supplies (SMPS) with minimal external parts count. The device integrates a high-voltage power supply regulator to allow operation without an auxiliary bias winding. An internal transconductance amplifier reduces external components for the flyback compensation circuit. The integrated PWM controller includes: 10-V regulator for implementation without external bias circuit, under-voltage lockout (UVLO) protection, leading-edge spacing (LEB), optimized gate on/off driver, EMI attenuator, high temperature shutdown Disconnect (TSD) protection for loop compensation temperature compensated precision current source, and fault protection circuits. Protections include: Overload Protection (OLP), Overvoltage Protection (OVP), Feedback Open Protection (FB_OLP), and Abnormal Overcurrent Protection (AOCP). The FSL306LRN provides excellent soft-start performance during start-up. An internal high voltage startup switch and Burst Mode operation with very low operating current reduce power loss in standby mode. Therefore, at an input voltage of 230 VAC, a power dissipation of 120 mW can be achieved without external bias and 25 mW with external bias.

The MC33035 is a high-performance, second-generation monolithic brushless DC motor controller that includes all effective functions required to implement a full-featured open-loop, three-phase or four-phase motor control system. The device includes a rotor position decoder for correct commutation sequence, temperature compensated reference capable of powering sensors, frequency programmable sawtooth oscillator, three open collector top drivers, and three high current totem pole bottom drivers , suitable for driving power MOSFETs. Protection features are also included with undervoltage lockout, cycle-by-cycle current limit shutdown mode with selectable time delay, internal thermal shutdown, and a unique fault output that can be interfaced into a microprocessor control system. Typical motor control functions include open loop speed, forward or reverse, run enable and dynamic braking. The MC33035 is designed to run brushless motors with electronic sensor phases of 60°/300° or 120°/240° and can also efficiently control brushed DC motors.
