The TL3842D-8 from Texas Instruments is an economy single-ended, current-mode PWM controller. It is optimized for off-line and DC-to-DC converters, offering features necessary for fixed-frequency current-mode control schemes with minimal external components.
This controller operates with a voltage range of 10V to 30V and supports topologies including Boost, Flyback, and Forward. It features an adjustable switching frequency up to 500kHz and a maximum duty cycle of 97%. Key internal circuits include undervoltage lockout (UVLO) with hysteresis, automatic feed-forward compensation, pulse-by-pulse current limiting, and a high-current totem-pole output stage.
The device is housed in an 8-SOIC package, suitable for surface mount applications. It operates within a temperature range of 0°C to 70°C.
Designed for interchangeability with UC2842 and UC3842 series, the TL3842D-8 provides features like current limiting and an error amplifier, making it a versatile choice for power management designs.
