The Analog Devices Inc. LTC3311 and LTC3311S use a constant frequency, peak current mode control architecture for fast transient response. A 500mV reference allows for low voltage outputs. 100% duty cycle operation delivers low dropout.
The LTC3311 and LTC3311S also 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.
The pin-compatible LTC3311 and LTC3311S Step-Down Silent Switchers are available in a compact 3mm x 3mm LQFN-18 package. Both variants are AEC-Q100 qualified for automotive applications.
