The UCC3813PW-1 is a high-speed, low-power integrated circuit designed for fixed-frequency current-mode switching power supplies. It operates with a typical starting supply current of 100¬µA and a typical operating supply current of 500¬µA, making it suitable for applications requiring efficient power management. The device supports operation up to 1MHz and features internal soft start and leading-edge blanking for improved performance. This controller is ideal for use in switch mode power supplies, DC-DC converters, and battery-operated power supply units. It is specified for an operating temperature range of 0¬8C to 70¬8C and is available in an 8-TSSOP package. The UCC3813PW-1 has a maximum duty cycle of 49% and operates with a supply voltage range of 7.4V to 12V. Its pin configuration is compatible with other devices in the UC384x family, facilitating design integration. Engineers considering this product should note its suitability for applications requiring a single output configuration and its compliance with halogen-free standards.
