The LM25011AMYE is a constant-on time non-synchronous Buck Regulator with adjustable current limit, features all the functions needed to implement an efficient buck bias regulator capable of supplying up to 2A of load current. This high-voltage regulator contains an N-channel Buck switch, a start-up regulator, current limit detection and internal ripple control. The constant on-time regulation principle requires no loop compensation, results in fast load transient response and simplifies circuit implementation. The operating frequency remains constant with line and load. The adjustable valley current limit detection results in a smooth transition from constant voltage to constant current mode when current limit is reached, without the use of current limit foldback. The PGD output indicates the output voltage has increased to within 5% of the expected regulation value.
● Integrated 2A N-channel buck switch
● Adjustable current limit allows for smaller inductor
● Minimum ripple voltage
● Power good output
● Adjustable soft-start timing
● Thermal shutdown
● Green product and no Sb/Br
●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
