LTC3307A/B Step-Down Silent Switcher™

Analog Devices Inc. LTC3307A/B Step-Down Silent Switcher™ is a very small, high-efficiency, low-noise, monolithic synchronous 3A step-down DC-DC converter operating from a 2.25V to 5.5V input supply. Using constant frequency, peak current mode control at switching frequencies of up to 3MHz, and minimum on-time as low as 22ns, the LTC3307A/B achieves fast transient response with small external components. The Silent Switcher architecture also minimises EMI emissions.
