illustrate
The LM34930 switching regulator's constant on-time step function requires a low-cost, high-efficiency, buck bias regulator capable of delivering more than 1A of load current. This high voltage regulator contains an N-channel buck switch and a packet bumper in μSMD. The regulatory principle of constant on-time requires fast load transient response, no loop compensation as a result, and simplified circuit implementation. The line and load of the operating frequency remain unchanged. Valley constant voltage constant current mode is the result of a smooth transition of current limiting when the current limit is detected without the current limit foldback. In order to reduce the saturation of the inductor's valley current limit threshold as the likelihood of an increase in the input voltage decreases, and when a current limit is detected, the time on is reduced. Other features include overvoltage specification, input overvoltage shutdown, VCC undervoltage lockout, thermal shutdown, and maximum duty cycle limit.
