DESCRIPTIOn  描述

The LTC®3605 is a high efficiency, monolithic synchronous buck regulator using a phase lockable controlled on-time constant frequency, current mode architecture. PolyPhase operation allows multiple LTC3605 regulators to run out of phase while using minimal input and output capacitance. The operating supply voltage range is from 15 V down to 4 V , making it suitable for dual lithium-ion battery inputs as well as point of load power supply applications from a 12 V or 5 V rail.
LTC®3605是一款高效率、单芯片同步降压稳压器，采用锁相控制导通时间恒定频率、电流模式架构。多相操作允许多个LTC 3605稳压器在使用最小输入和输出电容的同时异相运行。工作电源电压范围为15 V至4 V，适合双锂离子电池输入以及12 V或5 V供电轨的负载点电源应用。
The operating frequency is programmable from 800 kHz to 4 MHz with an external resistor. The high frequency capability allows the use of small surface mount inductors. For switching noise sensitive applications, it can be externally synchronized from 800 kHz to 4 MHz . The PHMODE pin allows user control of the phase of the outgoing clock signal. The unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that are operating at high frequency while demanding fast transient response. Two internal phase-lock loops synchronize the internal oscillator to the external clock and also servos the regulator on-time to lock on to either the internal clock or the external clock if it’s present.
工作频率可通过外部电阻在800 kHz至4 MHz范围内编程。高频能力允许使用小型表面贴装电感器。对于开关噪声敏感应用，它可以在800 kHz至4 MHz范围内进行外部同步。PHMODE引脚允许用户控制输出时钟信号的相位。独特的恒定频率/受控导通时间架构非常适合在高频率下工作并要求快速瞬态响应的高降压比应用。两个内部锁相环使内部振荡器与外部时钟同步，并使稳压器的工作时间锁定到内部时钟或外部时钟（如果存在）。
