Overview
The UC1856, UC2856, and UC3856 are high-performance current mode PWM controllers designed for speed and accuracy. They are pin-for-pin compatible with the UC3846 series and offer improved features such as fast 1.5A peak output stages, a low impedance TTL compatible sync output, and a trimmed oscillator current for accurate frequency and dead time control.
Key Features
Improved Current Sense Amplifier: With reduced noise sensitivity and a differential current sense with 3V common mode range.
Fast Output Stages: 1.5A peak output stages for rapid switching of power FETs.
Accurate Shutdown Threshold: 1V, 5% shutdown threshold for precise control.
ESD Protection: 4kV minimum ESD protection on all pins.
Applications
The UC1856, UC2856, and UC3856 are suitable for a wide range of applications, including power supplies, DC-DC converters, and motor control systems.
