OLINAS News: No LTM2987-16 Channel μModule PMBus Power System Manager

Eight clock outputs that can be set to eight phases.

**Overview** The LTC6909 features eight individual outputs, providing up to eight rail-to-rail 50% duty cycle clock signals. These outputs can be used to enable/disable multiple switching regulators or to achieve phase synchronization. Phase synchronization offers numerous design advantages, including improved EMI performance, reduced input and output ripple current, and enhanced load transient response. Additionally, by using three logic inputs, the phase relationship between these outputs can be set within a range of 45° to 120°, or the outputs can be set to logic "L" or high-impedance state. A single resistor is used to select the output frequency in the range of 12.5 kHz to 6.67 MHz. The LTC6909 also includes a Spectrum Spread Frequency Modulation (SSFM) feature, which is a technique for modulating the clock frequency with a pseudo-random signal. SSFM can be easily enabled and provides a method to reduce peak electromagnetic radiation. The amount of frequency spreading is fixed at ±10% of the center frequency, and the user can select one of three modulation rates.

SPACECOOL Co., Ltd. is pleased to announce its support for the purpose of the newly established memorial day "Day to End the Too Hot Summer" by the Japan Climate Leaders Partnership (JCLP). In order to address the increasingly severe heat waves, we will continue to promote the expansion of our zero-energy cooling radiative cooling material "SPACECOOL." JCLP has registered August 8, 2025, and every August 8 thereafter, as "Day to End the Too Hot Summer" with the Japan Anniversary Association. — What is the new memorial day "Day to End the Too Hot Summer"? In recent times, many regions in Japan have been experiencing consecutive days of extreme heat, and the impacts of climate change are manifesting in serious ways in our lives. Nevertheless, reports and discussions linking this to "climate change" are limited, and there is currently a lack of momentum for climate change measures. In response to this issue, JCLP has decided to establish the "Day to End the Too Hot Summer" during this hottest time of the year, creating a social impetus to reframe "heat" as a climate change issue. This memorial day aims to share the commitment to halt the climate crisis for future generations and serve as a starting point for advancing the systemic transformation of society as a whole.
