ANALOG DEVICES LT8607IDC#TRMPBF DC-DC Switching Synchronous Buck Regulator, Adjustable, 3V to 42V in, DFN-EP-8

LT8607IDC#TRMPBF is a compact, high-efficiency, high-speed synchronous monolithic step-down switching regulator that consumes only 1.7µA of non-switching quiescent current. Capable of delivering 750mA of continuous current, the LT8607 features Burst Mode operation, enabling high efficiency even at very low output currents while keeping the output ripple below 10mVP-P. Internal compensation with peak current mode topology allows the use of small inductors, resulting 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 LT8607, reducing the input supply current to 1µA. Applications include general-purpose step-down converters and low EMI step-down applications.

• Wide input voltage range from 3.0V to 42V, spread spectrum frequency modulation for low EMI
• Low dropout, peak current mode operation, accurate 1V enable pin threshold
• Internal compensation, output soft-start and tracking, allows use of small inductors
• Programmable output voltage, burst mode operation (sync functionality)
• Oscillator frequency is 200KHz typical at (RT = 221K, ILOAD = 350mA)
• Top power NMOS on-resistance is 375mohm typical at (ILOAD = 500mA, TA = 25°C)
• Minimum on-time is 35ns typical at (LOAD = 500mA, SYNC = 0V)
• SW leakage current is 5µA maximum at (VIN = 36V, TA = 25°C)
• EN/UV pin current is ±20nA maximum at (VEN/UV = 2V, TA = 25°C)
• Operating junction temperature range from -40°C to 125°C, 8-lead plastic DFN package
