The TL3845DR from Texas Instruments is an economy single-ended, current mode PWM controller. It is optimized for use in off-line and DC-to-DC converter applications, requiring a minimal number of external components for implementation.
Key electrical specifications include an operating voltage range of 7.6V to 30V, a maximum duty cycle of 48%, and an operating frequency of 100kHz. The device features undervoltage lockout (UVLO) with hysteresis, pulse-by-pulse current limiting, and double-pulse suppression. It also includes automatic feed-forward compensation and an error amplifier with low output resistance.
This controller is housed in a 14-SOIC package and is designed for surface mount applications. The operating temperature range is from 0°C to 70°C (TA). The TL3845DR is designed to be interchangeable with the UC2842 and UC3842 series controllers, offering design flexibility.
Features such as low start-up current (< 1mA), high-current totem-pole output, and an internally trimmed bandgap reference contribute to its performance and efficiency in power management designs.
