MIC2297 Détails du produit

General Description
The MIC2297 is a 600KHz PWM boost-switching regulator that is optimized for driving 6-10 series white LEDs. With its internal 40V switch and a guaranteed switch current of 1.2A, the MIC2297 easily drives a string of 10 white LEDs in series at 20mA, ensuring a high level of brightness and eliminating several ballast resistors.

Features
• 2.5V to 10V input voltage range
• Output voltage up to 40V
• 1.2A switch current
• 600KHz PWM operation
• Trimmed 200mV feedback voltage
• Output over voltage protection (fixed or adjustable)
• PWM Brightness Control
• DAC Brightness Control
• <1% line regulation
• 1µA shutdown current
• Over temperature protection
• UVLO
• 10-pin 2.5mm x 2.5mm MLF® package
• –40°C to +125°C junction temperature range

Applications
• PDAs
• GPS systems
• Smart phones
• Mini PCs
• Digital cameras
• IP phones
• LED flashlights
