UC1856-SP
Overview
The UC1856 is a high-performance version of the popular UC1846 series of current-mode controllers, and is intended for both design upgrades and new applications where speed and accuracy are important. All input-to-output delays have been minimized, and the current sense output is slew-rate limited to reduce noise sensitivity.
- 1 Pin-for-Pin Compatible With the UC1846
- 65-ns Typical Delay From Shutdown to Outputs, and 50-ns Typical Delay From SYNC to Outputs
- Improved Current-Sense Amplifier With Reduced Noise Sensitivity
- Differential Current Sense with 3-V Common- Mode Range
- Trimmed-Oscillator Discharge Current for Accurate Deadband Control
- Accurate 1-V Shutdown Threshold
- High-Current Dual Totem-Pole Outputs (1.5-A peak)
- TTL Compatible Oscillator SYNC Pin Thresholds
