Product Overview

The LTC3536EMSE#PBF is a 1A low noise synchronous buck-boost DC/DC Converter operates from input voltages above, below or equal to the regulated output voltage. The topology incorporated in the LTC3536 provides low noise operation, making it ideal for RF and precision measurement applications. The device can produce up to 1A of continuous output current and it includes two N-channel and two P-channel MOSFET switches. Switching frequencies up to 2MHz can be programmed with an external resistor and the oscillator can be synchronized to an external clock. Quiescent current is only 32µA in Burst Mode® operation, maximizing battery life in portable applications. Burst Mode® operation is user controlled and improves efficiency at light loads. Other features include a 1µA shutdown current, internal soft-start, over-temperature protection and current limit.
  • Regulated output with input voltages above, below or equal to the output
  • 1A Continuous output current for VIN >=3V, VOUT = 3.3V
  • ±1% Output voltage accuracy
  • Low noise buck-boost architecture
  • Up to 95% efficiency
  • Programmable frequency from 300kHz to 2MHz
  • Synchronizable oscillator
  • Burst Mode® operation (IQ = 32µA)
  • Internal 1ms soft-start
  • Output disconnect in shutdown
  • 1µA Shutdown current
  • Short-circuit protection
