In summary, the LTC33xx family are very small, low noise, monolithic step-down DC/DC converters that employ Silent Switcher 1 or 2 architecture with internal hot loops bypass capacitors to achieve both low EMI and high efficiency switching frequencies as high as 5MHz. For systems with higher power requirements, multi-phasing parallel converters are readily implemented. Other features include a power good signal when the output is in regulation, precision enable threshold, output overvoltage protection, thermal shutdown, a temperature monitor, clock synchronization, mode selection and output short circuit protection.
