Frequently Asked Questions
What is the UC2845AD8 used for?
UC2845AD8 is a current-mode PWM controller used in isolated flyback, forward, and boost converter designs. It provides cycle-by-cycle overcurrent limiting, a totem-pole gate driver with 1A peak current, and an oscillator programmable up to 1MHz, making it ideal for SMPS in industrial and telecom power supplies.
What package and pin count does UC2845AD8 have?
UC2845AD8 comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. The 8 pins include COMP, VFB, CS, RT/CT, GND, OUT, VCC, and VREF, matching the standard UC284x pinout.
What is the operating temperature range of UC2845AD8?
UC2845AD8 is the commercial-grade variant with an operating temperature range of 0°C to 70°C. For industrial applications requiring -40°C to 85°C, consider the UC3845AD8, or UC1845AD8 for -55°C to 125°C.
What are compatible alternates to UC2845AD8?
Pin-compatible alternates include UC3845AD8 (industrial -40°C to 85°C), UC2843AD8 (fixed 50% max duty cycle), and ON Semiconductor NCP2845DR2G. All share the same 8-pin SOIC footprint and UC284x control architecture.
