Frequently Asked Questions
What is the input voltage range of the UC2524AJ?
The UC2524AJ operates with an input voltage range from 1V minimum to 40V maximum, with a nominal input voltage of 20V. This wide range provides design flexibility for use across multiple power bus standards, from low-voltage battery systems up to 40V industrial power rails.
What control method does the UC2524AJ use for power conversion?
The UC2524AJ uses voltage-mode pulse width modulation (PWM) control. In this scheme, the output duty cycle is regulated by comparing a voltage-error amplifier output against a fixed-frequency sawtooth waveform, providing stable and predictable closed-loop regulation suitable for a wide range of DC-DC converter topologies.
What package does the UC2524AJ use and is it suitable for harsh environments?
The UC2524AJ is housed in a 16-pin ceramic dual in-line package (CDIP), identified by JESD-30 code R-GDIP-T16. The hermetically sealed ceramic package provides excellent protection against moisture, contamination, and temperature extremes, making it appropriate for military, aerospace, and industrial applications with harsh environmental conditions.
What is the maximum output current of the UC2524AJ?
The UC2524AJ provides a maximum output drive current of 200 mA. This output current capability is sufficient to directly drive the gate of small to medium power MOSFETs in many switching converter topologies, potentially eliminating the need for an external gate driver buffer stage in lower-power designs.
