The LTC3536 is an extended VIN range, fixed frequency, synchronous buck-boost DC/DC converter that 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, overtemperature protection and current limit. The LTC3536 is available in 12-pin thermally enhanced MSOP and 10-pin (3mm × 3mm) DFN packages.

Applications

  • Wireless Inventory Terminals
  • Handheld Medical Instruments
  • Wireless Locators, Microphones
  • Supercapacitor Backup Power Supply

LTC3536EMSE (MSOP) Demo Board | 1.8V ≤ VIN ≤ 5.5V, VOUT = 3.3V @ 1A

LTC3536EMSE (MSOP) Demo Board | 1.8V ≤ VIN ≤ 5.5V, VOUT = 3.3V @ 1A

Product Detail

Demonstration circuit 1852A is a combined step-up and step-down DC/DC converter, using the LTC3536 monolithic synchronous buck-boost regulator in the MSOP package. The DC1852A has wide input voltage range of 1.8V to 5.5V and is capable of delivering up to 1A of output current. The output voltage of the DC1852A can be set as low as 1.8V and can go as high as 5.5V. DC1852A supports two operation modes: fixed-frequency pulse-width modulation (PWM) and Burst Mode® operation.
