UC3833L Description
The UTC UC3833L is a high performance current Mode PWM controller, which is built-in with frequency triple, multi-protections and EMI-improved solution in a SOT-26 package. It’s ideal for applications requiring a cost-effective solution, minimum ponent counts and circuit space. The internal slope pensation improves system stability at high PWM duty cycle output.
UC3833L Key Features
- Very low startup current (<18µA)
- Ultra low operating current at light load (<1mA)
- Frequency triple for peak power (195kHz)
- Adjustable soft start time
- Adjustable OLP (over load protection) delay timer(automatic recovery)
- UVLO (Under Voltage Lockout)
- LEB (Leading-Edge Blanking) on CS Pin
- Current mode control with Green Mode Operation out pin clamping
- OVP (Over Voltage Protection) on VDD Pin ( latch shut down in UTC UC3833L)
- Internal frequency swapping for EMI improved
