                                                                                                    LTC®3616 is a low quiescent current monolithic synchronous buck regulator using a current mode, constant frequency architecture. The no-load DC supply current in sleep mode is only 70µA while maintaining the output voltage (burst mode operation) at no load, dropping to zero current in shutdown. The 2.25V to 5.5V input supply voltage range makes this ideally suited for single Li-Ion as well as fixed low voltage input applications. 100% duty cycle capability provides low dropout operation, extending the operating time in battery-powered systems. The operating frequency is externally programmable up to 4MHz, allowing the use of small surface mount inductors. Adjustable compensation allows the transient response to be optimized over a wide range of loads and output capacitors. Typical applications are point-of-load supplies, distributed power supplies, portable computer systems, DDR memory termination, handheld devices.
