IP2501

Ultra low I_Q400mA High Efficiency Synchronous Step-up Converter



Wearable Device, MID

1. Features

3. Description



Ultra low I_Q, Typical Quiescent Current 1.5μA

The IP2501 is a fixed PWM frequency, high

efficiency synchronous step-up converter, it

provide a power supply solution for products

three-cell alkaline, NiCd or NiMH, or one-cell

Li-ion or Li-polymer battery. At low load

currents, the IP2501 exits the fixed switching

frequency mode and enter the power-down

mode to maintain a high efficiency over a

wide load current range. The IP2501 provide a

wide output voltage range by adjusting the

feedback resistor divider. During shutdown,

the load is completely disconnected from the

battery, and the quiescent current is less than

1.5μA to ensure the battery capacity.

Ultra low Operating Input Voltage 0.9V, Wide

Input Voltage Range 0.7V-5.5V

Wide Adjustable Output Voltage Range up to

5.5V



Up to 96% Efficiency

Output Voltage Accuracy ±2%

Maximum 400mA Output Current

Internal Synchronous Rectifier

True Shutdown Mode

Thermal Shutdown

Short Circuit Protection

SOT23-6 Package

2. Applications



All One-Cell, Two-Cell, and Three-Cell Alkaline,

NiCd or NiMH

The IP2501 is packaged in a 6-pin thin SOT23

package.
