Soft-start mode, avoid the humidity make the heater burn out.
The MAX15023 also allows prebiased startup without discharging the output andfeatures adaptive internal digital soft-start.
Programmable soft-start allows the user to reduce the inrush currents.
Using the PMBus standard, the TPS40428 device can program reference voltage, fault limit,UVLO threshold, soft-start time and turn-on and turn-off delay.
Soft-start and automatic emergency stop design to protect the operator.
For example, certain settings such as the switching frequency or the soft-start time should be adjustable, the circuit must be told what to do.
Soft-start feature reduces torque at start-up and motor maintains constant speed under load.
The MAX5003 offers some distinctive advantages: soft-start, undervoltage lockout, external frequency synchronization, and fast input voltage feed-forward.
Soft-start and shutdown waveforms for the MAX1561 boost converter(a) and MAX1573 charge pump(b) show no input current(IIN) overshoot.
The output-voltage startup ramp is controlled by the soft-start pin, which allows operation as either a standalone power supply or in tracking configurations.
The soft-start pin controls the output voltage start-up ramp, which allows operation either as a standalone power supply or in tracking configurations.
For sequencing purpose, the device features adjustable soft-start time, programmable EN/UVLO threshold, and a power-good indicator Active-Low RESET pin.
Soft-start can be implemented using the shutdown pin with an external RC circuit allowing the user to tailor the soft-start time to a specific application.
Competitive features include very low external-component count, fast load-transient response, auto-skip mode operation,internal soft-start control, and no requirement for compensation.
(1) Power Saver uses soft-start function to reduce 4-7 times the starting current.
Expanded system level protections feature input brownout and dropout recovery, output over-voltage, open-loop,overload, soft-start, phase-fail detection, and thermal shutdown.
