Ürün Genel Bakış

The LM2651MTC-ADJ is a Switching Regulator provides high-efficiency power conversion over a 100:1 load range. This feature makes the LM2651 an ideal fit in battery-powered applications that demand long battery life in both run and standby modes. Synchronous rectification is used to achieve up to 97% efficiency. At light loads, the LM2651 enters a low power hysteretic or sleep-mode to maintain high efficiency. In many applications, the efficiency still exceeds 80% at 15mA load. A shutdown pin is available to disable the LM2651 and reduce the supply current to less than 10µA. The LM2651 contains a patented current sensing circuitry for current-mode control. This feature eliminates the external current sensing resistor required by other current-mode DC-to-DC converters. The LM2651 has a 300kHz fixed frequency internal oscillator. The high oscillator frequency allows the use of extremely small, low-profile components.
  • Patented current sensing for current-mode control
  • Input undervoltage lockout
  • Adjustable soft-start function
  • Current limit and thermal shutdown
  • Ultrahigh efficiency up to 97%
  • Internal MOSFET switch with low RDS(on) of 75mR
  • 7µA Shutdown current
