LM25011 all the functions required for a fixed-on-time buck-switching regulator to achieve low-cost functionality and high efficiency, buck-bias regulators provide up to 2A of load current capability. This high voltage regulator contains an N-channel buck switch, starting the regulator, current limit detection, control, and internal fluctuations. The principle of constant on-time regulation eliminates the need for loop compensation for fast load transient response, resulting in a simplified circuit design. The operating frequency maintains a constant line and load. Adjustable valley current limit when the current reaches the limit when the current is reached in a smooth transition to constant voltage and constant current mode, and the test results are not folded back current limit. Diagnostic output prior to embryo implantation indicates an increase in output voltage at an expected regulatory value of 5%. Other features include: low output ripple, VIN undervoltage lockout, adjustable soft-start time, thermal shutdown, gate drive precharge, gate drive undervoltage lockout, and maximum duty cycle limit.
The LM25011A has a specific LM25011, which allows for minimal shutdown time at low input voltages for high-frequency operation.
