LT8630
100V, 0.6A Synchronous
Micropower Step-Down
High Efficiency Switching Regulator
Description Features 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 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. Ultrawide Input Voltage Range: 3V to 100V …
