TDA168462HKLA1

Power Supply Controllers, Monitors Overview

The TDA16846-2 is a power supply controller optimized for controlling free-running or fixed-frequency flyback converters with or without Power Factor Correction (Current Pump). It supports low-power standby applications by reducing switching frequency in small steps as load decreases, reaching an adjustable minimum such as 20 kHz in standby mode. The device operates within a supply voltage range of 8V to 16V and draws a supply current of 5 mA. It is housed in a 14-DIP package and functions across a temperature range of -25°C to 125°C.
