Product Description

The UC2825ADW is a high speed Pulse Width Modulation (PWM) Controller, an improved versions of the standard UC3825 family. Performance enhancements have been made to several of the circuit blocks. Error amplifier gain bandwidth is 12MHz, while input offset voltage is 2mV. Current limit threshold is assured to a tolerance of 5%. Oscillator discharge current is specified at 10mA for accurate dead time control. Frequency accuracy is improved to 6%. Startup supply current, typically 100µA, is ideal for off-line applications. The output drivers are redesigned to actively sink current during UVLO at no expense to the startup current specification. In addition each output is capable of 2A peak currents during transitions. The UC3825 shutdown comparator is now a high-speed overcurrent comparator with a threshold of 1.2V. The overcurrent comparator sets a latch that ensures full discharge of the soft-start capacitor before allowing a restart.
Compatible with voltage-mode or current-mode control methods
50ns Propagation delay to output
High-current dual totem pole outputs (2A peak)
Trimmed oscillator discharge current
Low 100µA Startup current
Pulse-by-pulse current limiting comparator
Latched overcurrent comparator with full cycle restart
Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
