The TL3845 is a high-performance current-mode pulse-width modulation (PWM) controller IC, optimized for off-line and DC-DC converter applications. Designed for efficient switching power supplies, this IC combines a high-gain error amplifier, a precision voltage reference, and a current-sensing comparator for cycle-by-cycle current limiting.
With features like undervoltage lockout (UVLO), short-circuit protection, and a totem-pole output stage for driving power MOSFETs or BJTs, the TL3845 ensures robust and reliable power regulation. It offers fast transient response and supports high-frequency operation, making it suitable for compact and energy-efficient power supplies.
