LT8630

100V, 0.6A Synchronous Micropower

Step-Down High Efficiency Switching Regulator

FEATURES

DESCRIPTION

The LT^®8630 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 automo-

tive and industrial systems and 36V to 72V telecom sup-

plies. Variable frequency boundary mode switching maxi-

mizes efficiency across a wide range of input voltages.

Low ripple Burst Mode operation enables high efficiency

operation down to very low output currents while keep-

ing 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 provid-

ing 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 cur-

rent to < 5µA. The LT8630 is available in a 20-lead TSSOP

package with exposed pad for low thermal resistance and

high voltage lead spacing.
