This document introduces the features and characteristics of UC1524, UC2524 and UC3524. They can be used to construct regulating power supplies, inverters or switching regulators. They can also be used as the control element for high-power-output applications.
The UC1524 family of devices incorporates all functions required for constructing regulating power supplies, inverters, or switching regulators on a single monolithic chip. These fixed-frequency pulse-width modulation controllers utilize dual alternating outputs suitable for either single-ended or push-pull applications.
Key features include an on-chip 5V reference, error amplifier, programmable oscillator, and current-limiting/shut-down circuitry. The UC1524 is characterized for military temperature ranges (-55°C to +125°C), while the UC2524 and UC3524 are designed for commercial industrial applications with lower temperature ratings.
| Operating Junction Temperature (UC1524) | -55°C to +150°C |
|---|---|
| Maximum Frequency | 300 kHz |
| Open Loop Voltage Gain (Min/Max) | 72 dB to 80 dB |
Yes, the dual alternating outputs allow either single-ended or push-pull applications.
