The LT8609SIV#PBF from Linear Technology is a 42V, 2A/3A peak synchronous step down regulator with 2.5μA quiescent current in 16 pin LQFN package. This is a compact, high efficiency, high speed synchronous monolithic step down switching regulator that consumes only 1.7μA of non-switching quiescent current. It can deliver 2A of continuous current with peak loads of 3A (<1sec) to support applications such as GSM transceivers which require high transient loads. Top and bottom power switches are included with all necessary circuitry to minimize need for external components. 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

• Wide input voltage range from 3V to 42V
• Silent Switcher? 2 architecture, ultralow EMI/EMC emissions on PCB, eliminate PCB layout sensitivity
• Internal bypass capacitors reduce radiated EMI, optional spread spectrum modulation
• High efficiency 2MHz synchronous operation, >93% efficiency at 1A, 12VIN to 5VOUT
• 2A maximum continuous output, 3A peak transient output
• Fast minimum switch-on time is 45ns at ILOAD = 1.5A, SYNC = 0V
• Adjustable and synchronizable frequency of 200KHz to 2.2MHz
• Allows use of small inductors, low dropout, peak current mode operation
• Internal compensation, output soft-start and tracking
• Operating temperature range from -40°C to 125°C
