Unisonic Technologies UC3833L
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 component counts and circuit space. The internal slope compensation improves system stability at high PWM duty cycle output.| Part No. | UC3833L |

DESCRIPTION
The UTC The UTC UC3833L incorporates frequency triple function and adjustable OLP timer to handle the peak power with delay time. The frequency triple function can reduce the transformer flux and core size. Furthermore, the frequency swapping function is to reduce the noise level and thus helps the power circuit designers for EMI suppression with minimum amount of component cost and developing time. 54 6 1 23 SOT-26●
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 * ON-Chip OTP (Over Temperature Protection, latch shut down in UTC...
