LT8631EFE#PBF

LT8631 is a current mode PWM step-down DC/DC converter with internal synchronous switches that provide current for output loads upto 1A. Low ripple Burst Mode operation enables high efficiency operation down to very low output currents while keeping the output ripple below 10mVP-P. Resistor programmable 100KHz to 1MHz frequency range and synchronization capability enable optimization between efficiency and external component size. The soft-start feature controls the ramp rate of the output voltage, eliminating input current surge during start-up, while also providing output tracking. A power good flag signals when the output voltage is within ±7.5% of the regulated output. Undervoltage lockout can be programmed using the EN/ UV pin. It is widely used in application such as automotive supplies, telecom supplies, distributed supply regulation etc.
