The Texas Instruments LM5021-1 is a high-performance AC/DC Current-Mode PWM Controller designed for efficient offline single-ended flyback and forward power converters. It boasts an ultra-low start-up current of 25µA maximum, minimizing power loss in the high voltage start-up network.
Key features include current mode control, skip cycle mode for low standby power, a single resistor programmable oscillator capable of 1MHz, and an integrated 0.7A peak gate driver. The controller also offers adjustable soft-start, direct opto-coupler interface, and maximum duty cycle limiting of 80% for the LM5021-1 variant.
Additional protective features include under-voltage lockout (UVLO) with hysteresis, cycle-by-cycle current limit, hiccup mode for overload protection, and leading edge blanking of the current sense signal. The device operates over a temperature range of -40 to 125°C.
The LM5021-1 is available in a VSSOP-8 package, suitable for surface mount applications.
