MCP1253 Product details

Description
The MCP1252/3 are inductorless, positive-regulated charge pump DC/DC converters. The devices generate a regulated fixed (3.3V or 5.0V) or adjustable output voltage. They are specifically designed for applications requiring low noise and high efficiency and are able to deliver up to 120 mA output current. The devices allow the input voltage to be lower or higher than the output voltage, by automatically switching between buck/boost operation.

Features
• Inductorless, Buck/Boost, DC/DC Converter
• Low Power: 80 µA (Typical)
• High Output Voltage Accuracy:
    - ±2.5% (VOUT Fixed)
• 120 mA Output Current
• Wide Operating Temperature Range:
    - -40°C to +85°C
• Thermal Shutdown and Short-Circuit Protection
• Uses Small Ceramic Capacitors
• Switching Frequency:
    - MCP1252: 650 kHz
    - MCP1253: 1 MHz
• Low Power Shutdown Mode: 0.1 µA (Typical)
• Shutdown Input Compatible with 1.8V Logic
• VIN Range: 2.0V to 5.5V
• Selectable Output Voltage (3.3V or 5.0V) or Adjustable Output Voltage
• Space-saving, 8-Lead MSOP
• Soft-Start Circuitry to Minimize In-Rush Current

Applications
• White LED Backlighting
• Color Display Bias
• Local 3V-to-5V Conversions
• Flash Memory Supply Voltage
• SIM Interface Supply for GSM Phones
• Smart Card Readers
• PCMCIA Local 5V Supplies
