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 component counts and circuit space.

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 * ON-Chip OTP (Over Temperature Protection, latch shut down in UTC UC3833L)
