Description

General part information

LT8630 Series

The LT8630 is a current mode PWM step-down DC/DC converter with internal synchronous switches that provide current for output loads up to 0.6A. The wide input range of 3V to 100V makes the LT8630 suitable for regulating power from a wide variety of sources, including automotive and industrial systems and 36V to 72V telecom supplies. Variable frequency boundary mode switching maximizes efficiency across a wide range of input voltages. Low ripple Burst Mode operation enables high efficiency operation down to very low output currents while keeping the output ripple below 5mV. 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. Shutdown mode reduces the total quiescent current to < 5μA. The LT8630 is available in a 20-lead TSSOP package with exposed pad for low thermal resistance and high voltage lead spacing.APPLICATIONSTelecom SuppliesDistributed Supply Regulation
