Features

* internal over voltage protection (OVP) and over current protection (OCP) circuits for increased system reliability. A precision enable pin and integrated UVLO allows the turn-on of the device to be tightly controlled and sequenced. Start-up inrush currents are limited by an internal Soft-Start circu

Applications

* The LM21305 provides 1% output-voltage accuracy and excellent line and fast load transient response for digital loads. The device offers flexible system configuration via programmable switching frequency and ability to synchronize switching frequency. The device also provides internal soft-start to
