ON Semiconductor MC33060APG - Voltage Mode PWM Controller

The MC33060APG from ON Semiconductor is a precision voltage mode Pulse Width Modulation (PWM) controller designed to cater to a wide array of power supply and direct current (DC) to direct current (DC) converter applications. This versatile integrated circuit (IC) is engineered to provide high-performance solutions for power management challenges.

With its ability to operate at a supply voltage range of 10 V to 30 V, the MC33060APG is well-suited for systems that require a stable and efficient power control. It features an oscillator with a frequency range that can be programmed from 100 Hz to 400 kHz, giving designers the flexibility to tailor the performance to their specific needs. The oscillator's frequency can be adjusted via external components, which allows for fine-tuning and precise control over the power supply's operation.

The MC33060APG also includes a variety of protective features to ensure the longevity and reliability of the application it is used in. These include an undervoltage lockout (UVLO) with hysteresis, a pulse-by-pulse current limiting function, and a thermal shutdown mechanism. The UVLO ensures that the IC operates only when the supply voltage is sufficient, preventing malfunction due to power dips. The current limiting protects against overcurrent conditions, while the thermal shutdown feature prevents overheating and potential damage to the device.

Additional features of this PWM controller include a 1.5 A output drive capability, which is suitable for driving a power MOSFET or IGBT directly. The device also provides a high gain error amplifier, a fast current sense comparator, and a latch for single pulse metering. These features make the MC33060APG a robust solution for designing efficient power supplies, switch mode power supplies (SMPS), and other power conversion applications.

Enclosed in an 8-pin PDIP package, the MC33060APG offers a compact footprint for space-conscious designs. Its operational temperature range of 0°C to +70°C ensures stable performance in a variety of environmental conditions. For designers looking for a reliable and flexible PWM controller, the MC33060APG from ON Semiconductor is an excellent choice that combines performance with protective features to deliver a dependable power management solution.
