Product Overview
LTC®3311 is a very small low noise monolithic synchronous step-down DC/DC converter capable of providing up to 12.5A of output current from a 2.25V to 5.5V input supply. This device employs silent switcher 1 architecture to achieve both low EMI and high efficiency at switching frequencies as high as 5MHz. For systems with higher power requirements, multi-phasing parallel converters is readily implemented. This LTC3311 uses 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 drop out. 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.
- Pin compatible with LTC3310/LTC3310S and LTC3311S, ultralow EMI emissions
- High efficiency-4.5mohm NMOS and 16mohm PMOS
- Wide bandwidth, fast transient response, power good output
- Safely tolerates inductor saturation in overload, die temperature monitor
- VOUT accuracy of ±1% with remote sense, -40°C to 150°C temperature range
- Peak current mode control, minimum on-time of 35ns
- Precision 400mV enable threshold, 1µA in shutdown, output soft-start with voltage tracking
- Configurable for paralleling power stages in forced continuous mode
