The TL2842BD-8 from Texas Instruments is a high-performance current-mode PWM controller. It is designed to facilitate the implementation of off-line or DC-to-DC fixed-frequency current-mode control schemes with minimal external components.
Key electrical characteristics include an operating voltage range of 10V to 30V and a maximum operating frequency of up to 500kHz. The device supports a maximum duty cycle of 96% and operates within an ambient temperature range of -40°C to 85°C.
Internally, the controller features an undervoltage lockout (UVLO), a precision trimmed reference, and a latched PWM comparator for cycle-by-cycle current limiting. The output stage is a high-current totem-pole design suitable for driving N-channel MOSFETs.
This component is supplied in an 8-SOIC package, designed for surface mounting. Its features make it suitable for various switching regulator applications of any polarity and transformer-coupled DC/DC converters.
