Product Overview

LTC®3310S is a very small, low noise, monolithic step-down DC/DC converter. The device employs internal hot loop bypass capacitors 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. The LTC3310S 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 dropout. 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. Typical applications are automotive/industrial/communications, servers, telecom power supplies, distributed DC power systems (POL), FPGA, ASIC, µP core supplies.
  • Silent switcher®2 architecture: ultralow EMI emissions
  • Wide bandwidth, fast transient response
  • Safely tolerates inductor saturation in overload, shutdown current is 1µA
  • Peak current mode control, output soft-start with voltage tracking
  • Power good output, die temperature monitor, error amp transconductance is 400µS
  • Configurable for paralleling power stages, programmable frequency to 5MHz
  • Adjustable output voltage (0.5V to VIN)
  • Operating supply voltage is 2.25 to 5.5V at TA = 25°C, VIN = 3.3V
  • 18-lead (3mm × 3mm) LQFN (laminate package with QFN footprint)
  • -40°C to 125°C temperature rating, AEC-Q100 qualified for automotive applications
