Description
General part information
LTC3636LTC3636-1 Series
The LTC3636/LTC3636-1 is a high efficiency, dual-channel monolithic synchronous buck regulator using a controlled on-time current mode architecture, with phase lockable switching frequency. The operating supply voltage range is from 3.1V to 20V, making it suitable for lithium-ion battery stacks as well as point of load power supply applications from a 12V or 5V input.The operating frequency is programmable from 500kHz to 4MHz with an external resistor and may be synchronized to an external clock signal. The high frequency capability allows the use of small surface mount inductors and capacitors. The unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that operate at high frequency while demanding fast transient response.The LTC3636/LTC3636-1 can select between forced continuous mode and high efficiency Burst Mode operation. The LTC3636 and LTC3636-1 differ in their output voltage sense range.APPLICATIONSDistributed Power SystemsBattery-Powered InstrumentsPoint-of-Load Power Supplies
