The TL3842BDR from Texas Instruments is a high-performance current-mode PWM controller designed for efficient DC-to-DC conversion. It supports switching frequencies up to 500kHz, enabling the design of compact power supplies. The device operates over a voltage range of 10V to 30V and features a maximum duty cycle of 96%.
Key features include low start-up current, trimmed oscillator discharge current, and automatic feed-forward compensation. It also incorporates latching PWM for cycle-by-cycle current limiting and an internally trimmed reference with undervoltage lockout. The output stage is a high-current totem-pole design suitable for driving N-channel MOSFETs.
This controller is suitable for various switching regulator applications, including boost, flyback, and forward converters. It is available in a 14-SOIC surface mount package, making it suitable for space-constrained designs. The operating temperature range is 0°C to 70°C.
The TL3842BDR series offers improvements over standard controllers, such as specified low start-up current and trimmed oscillator discharge current. It is pin-compatible with standard TL284x and TL384x series.
