The LTC3605EUF#TRPBF from Analog Devices is a high-efficiency, monolithic synchronous buck regulator. It utilizes a phase-lockable, controlled on-time, constant frequency, current mode architecture. This regulator is suitable for point-of-load power supply applications from 12V or 5V rails, as well as dual lithium-ion battery inputs, with an operating supply voltage range from 4V down to 15V.
Key features include up to 96% efficiency, 5A output current capability, and an adjustable operating frequency programmable from 800kHz to 4MHz. This high frequency capability allows for the use of small surface mount inductors. The device also supports PolyPhase operation for multi-phase configurations and offers output tracking. It is available in a compact 24-pin (4mm x 4mm) QFN package, making it ideal for space-constrained designs.
The regulator's constant frequency/controlled on-time architecture is well-suited for high step-down ratio applications requiring fast transient response. It operates with integrated N-channel MOSFETs (70mΩ top and 35mΩ bottom) and provides excellent line and load transient response due to its current mode operation. In shutdown mode, it draws less than 15µA supply current.
