UC3845BNG PWM Controller IC is a high-performance pulse-width modulation (PWM) control IC, specifically designed for switch-mode power supplies (SMPS), DC-DC converters, and motor controllers. It belongs to the UC3842/UC3843/UC3844/UC3845 family, known for its high efficiency, precision, and minimal external component requirements.
With a fixed-frequency, current-mode PWM control scheme, the UC3845BNG IC ensures exceptional power efficiency and stability in industrial power management systems. It features a trimmed oscillator for accurate duty cycle control, a temperature-compensated reference voltage, and a high-gain error amplifier, making it an excellent choice for power electronics and automation applications.
The UC3845BNG PWM IC also includes a high-current totem-pole output for directly driving Power MOSFETs, low startup current for energy-efficient designs, a maximum duty cycle of 50% for precise power control, Under-Voltage Lockout (UVLO) at 8.5V (on) and 7.9V (off), and support for frequencies up to 500kHz for high-speed switching applications.
Packaged in a compact TO-220, this PWM controller IC is ideal for industrial power supplies, energy-efficient converters, and motor drive systems. Whether you're designing DC-DC converters, SMPS circuits, or voltage regulation systems, the UC3845BNG ensures optimized performance and stability.
