Frequently Asked Questions
What is the input voltage range of the UC2524ANG4?
The UC2524ANG4 operates with an input voltage range from 8V minimum to 40V maximum, with a nominal operating voltage of 20V. This wide range makes it compatible with various unregulated DC bus voltages commonly found in industrial and commercial power supply designs.
What is the maximum switching frequency of the UC2524ANG4?
The UC2524ANG4 supports switching frequencies up to 500 kHz. Higher switching frequencies allow for smaller magnetics and filter capacitors, resulting in more compact and cost-effective power supply designs compared to lower-frequency controllers.
What control mode does the UC2524ANG4 use?
The UC2524ANG4 uses voltage-mode pulse width modulation (PWM) control. This control technique compares the output voltage feedback signal against a sawtooth ramp to determine duty cycle, providing straightforward loop compensation and stable regulation across load conditions.
What package does the UC2524ANG4 come in?
The UC2524ANG4 is available in a 16-pin DIP (Dual In-Line Package), designated PDIP-T16. This through-hole package is convenient for prototyping and breadboard-based development, as well as production designs requiring easy manual assembly or socketed replacement.
What reference voltage output does the UC2524ANG4 provide?
The UC2524ANG4 provides an integrated 5.1V reference voltage output capable of sourcing up to 200 mA. This reference is used to bias internal control circuitry and can also power external components in the power supply control loop, reducing the need for external reference ICs.
