Frequently Asked Questions
What is the input voltage range of the LM2524DN/NOPB?
The LM2524DN/NOPB operates from an input voltage range of 8V to 40V with a nominal 20V design center, making it compatible with standard 12V and 24V industrial power rails as well as unregulated supplies that may vary significantly from their nominal values under load and line conditions.
What PWM control mode does the LM2524DN/NOPB use?
The LM2524DN/NOPB uses voltage-mode PWM control, where the duty cycle is determined by comparing an error amplifier output to a sawtooth oscillator ramp. Voltage-mode control provides simple loop compensation and is well-suited for designs requiring predictable frequency-domain behavior and reliable regulation under steady-state conditions.
What package does the LM2524DN/NOPB use?
The LM2524DN/NOPB is packaged in a 16-pin DIP (Dual In-Line Package), a through-hole format suitable for prototyping on breadboards, legacy production designs, and applications requiring manual or wave-soldered assembly. The DIP package also aids serviceability in industrial equipment where component replacement may be needed in the field.
What protection features does the LM2524DN/NOPB include?
The LM2524DN/NOPB includes an internal current limiting circuit that monitors and restricts peak switch currents to protect the power transistors from damage during overload or short-circuit conditions. Combined with the error amplifier's soft-start capability, these features enhance reliability and reduce stress on both the controller and the power stage components.
