3. Description
The IP2501 is a fixed PWM frequency, high
Input Voltage Range 0.7V-5.5V efficiency synchronous step-up converter, it
- Wide Adjustable Output Voltage Range up to provide a power supply solution for products
5.5V powered by either a one-cell, two-cell, or
- Up to 96% Efficiency three-cell alkaline, Ni Cd or Ni MH, or one-cell
- Output Voltage Accuracy ±2%
Li-ion or Li-polymer battery. At low load
- Maximum 400m A Output Current currents, the IP2501 exits the fixed switching
- Internal Synchronous Rectifier frequency mode and enter the power-down
- True Shutdown Mode mode to maintain a high efficiency over a
- Thermal Shutdown wide load current range. The IP2501 provide a
- Short Circuit Protection wide output voltage range by adjusting the
- SOT23-6 Package feedback resistor divider. During shutdown,
