UC1846J/883BC Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for the UC1846J/883BC is -55°C to 125°C, although it can withstand storage temperatures from -65°C to 150°C.

  • To ensure proper biasing, the UC1846J/883BC requires a minimum of 8.5V on the VCC pin and a maximum of 15V. The VREF pin should be decoupled with a 0.1uF capacitor to ground, and the RT pin should be connected to a resistor divider network to set the oscillator frequency.

  • The UC1846J/883BC can deliver a maximum output current of 1A per channel, making it suitable for driving small to medium-sized loads.

  • To synchronize multiple UC1846J/883BC devices, connect the RT pins of each device together and use a single resistor divider network to set the oscillator frequency. This ensures that all devices oscillate at the same frequency and are in phase with each other.

  • The soft-start pin (SS) allows the user to implement a soft-start or slow-start function, which helps to reduce inrush currents and stress on the power supply during startup. The SS pin can be connected to a capacitor and resistor network to create a slow-start ramp.
