LT8609SIV#PBF

LT8609S is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 1.7µA of non-switching quiescent current. Low ripple Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. A SYNC pin allows synchronization to an external clock, or spread spectrum modulation of switching frequencies for low EMI operation. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability. It is widely used in application such as general purpose step down, low EMI step down etc.

• Silent Switcher® 2 architecture, ultralow EMI emissions on any PCB
• Eliminates PCB layout sensitivity, internal bypass capacitors reduce radiated EMI
• Wide input voltage range is 3V to 42V
• Fast minimum switch-on time is 45ns typical
• Adjustable and synchronizable range is 200KHz to 2.2MHz
• Allows use of small inductors, low dropout, peak current mode operation
• Internal compensation, output soft-start and tracking
• 2A maximum continuous output, 3A peak transient output
• Operating temperature is -40°C to 125°C
• Packaging style is 16-lead LQFN
