Features:

• High-voltage operation up to 60V
• Wide input voltage range from 4.5V to 60V
• Fixed 50kHz switching frequency
• Internal oscillator with frequency (jitter) reduction
• Soft-start and burst mode operation
• Under-voltage lockout and over-temperature protection
• Short-circuit and over-current protection
• Small thermally enhanced DFN package

Applications:

• DC-DC converters
• Motor control
• Battery charging
• Power supplies for industrial and consumer electronics
• LED lighting
• Telecom power systems

The UC2854BMDWREP is a versatile and efficient PWM controller that can be used in a wide range of power conversion applications. Its high-voltage operation and integrated protection features make it a popular choice for designers looking for a reliable and easy-to-use solution.
