PJ30072 Synchronous Step-Up DC/DC Converter

PANJIT’s 5.5 V, 0.75 A, high-efficiency synchronous boost converter provides a complete power supply solution

Image of PANJIT PJ30072 Synchronous Step-Up DC/DC ConverterPANJIT’s PJ30072 is a synchronous step-up DC/DC converter based on constant Off Time/PSM controller topology using an internal synchronous rectifier to obtain maximum efficiency. The IC automatically enters PSM mode at light load, aiming to improve efficiency and reduce quiescent current. The PJ30072 provides a complete power supply solution for products powered by one or two alkaline, Ni-Cd, or Ni-MH battery cells. It stays in operation with supply voltages down to 0.7 V. A low-EMI mode is implemented to reduce ringing and, in effect, lowers radiated electromagnetic energy when the converter enters the discontinuous conduction mode.

Features
  • Deliver 3.3 V at 60 mA from a single alkaline/Ni-MH or 3.3 V at 120 mA from two cells
  • Up to 94% efficiency
  • Low shutdown current: <1 μA
  • Low quiescent current: 12 μA
  • Low no-load input current
  • Package: SOT23-6
Applications
  • Wireless mice
  • Medical instruments
  • Smartphones
  • Bluetooth devices
