Prezentare generală a produsului

The MCP16251T-I/CH is a compact high-efficiency fixed frequency synchronous step-up DC-DC Converter provides an easy-to-use power supply solution for applications powered by either one-cell, two-cell or three-cell alkaline, NiCd, NiMH, one-cell Li-ion or Li-polymer batteries. A low-voltage technology allows the regulator to start up without high inrush current or output voltage overshoot from a low voltage input. High efficiency is accomplished by integrating the low-resistance N-channel boost switch and synchronous P-channel switch. All compensation and protection circuitry are integrated to minimize external components. MCP16251 operates and consumes less than 14µA from battery, while operating at no load (VOUT = 3.3V, VIN = 1.5V). The devices provide a true disconnect from input to output (MCP16251) or an input-to-output bypass (MCP16252), while in shutdown (EN = GND). Both options consume less than 0.6µA from battery.
  • Up to 96% typical efficiency
  • 0.82V Low start-up voltage
  • Low operating input voltage down to 0.35V
  • Maximum input voltage, <VOUT <5.5V
  • Automatic PFM/PWM operation
  • PWM operation at 500kHz
  • <4µA Typical low device quiescent current
  • 0.6µA Typical shutdown current
  • Internal synchronous rectifier
  • Internal compensation
  • Inrush current limiting and internal soft-start
  • True load disconnect shutdown
  • Anti-ringing control
  • Over-temperature protection
ESD sensitive device, take proper precaution while handling the device.
