Description

General part information

LTC3616 Series

The LTC3616 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 the LTC3616 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. For switching noise-sensitive applications, the LTC3616 can be synchronized to an external clock at up to 4MHz.Forced continuous mode operation in the LTC3616 reduces noise and RF interference. Adjustable compensation allows the transient response to be optimized over a wide range of loads and output capacitors.The internal synchronous switch increases efficiency and eliminates the need for an external catch diode, saving external components and board space. The LTC3616 is offered in a leadless 24-pin 3mm × 5mm thermally enhanced QFN package.ApplicationsPoint-of-Load SuppliesDistributed Power SuppliesPortable Computer SystemsDDR Memory TerminationHandheld Devices
