LT8608EDC#TRMPBF

LT®8608 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 1.7µA of quiescent current. This can deliver 1.5A of continuous current. Low ripple Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mV. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability. The EN/UV pin has an accurate 1V threshold and can be used to program VIN undervoltage lockout or to shut down the LT8608. The PG flag signals when VOUT is within ±8.5% of the programmed output voltage aswell as fault conditions. Typical applications are general purpose step down, low EMI step down.

• Minimum input voltage is 2.5V typical
• High efficiency 2MHz synchronous operation, spread spectrum frequency modulation for low EMI
• <gt/>92% efficiency at 0.5A, 5VOUT from 12VIN, 1.5A continuous output current
• Allows use of small inductors, low dropout
• Peak current mode operation, accurate 1V enable pin threshold
• Internal compensation, output soft-start and tracking
• VIN quiescent current is 4µA at VEN/UV = 0V, VSYNC = 0V
• 8-lead (2mm × 2mm) plastic DFN package
• Temperature rating range from –40°C to 125°C
