The MIC2297-15YML-TR from Microchip Technology is a 600KHz PWM boost-switching regulator optimized for driving series white LEDs. It features an internal 40V switch with a guaranteed current of 1.2A, capable of driving up to 10 white LEDs in series at 20mA. This high-frequency PWM operation reduces external component sizes and minimizes noise and input ripple.
The regulator is designed for efficiency with a trimmed 200mV feedback voltage, reducing power dissipation in the current set resistor. It includes output over-voltage protection to safeguard against open LED conditions. The device operates within a 2.5V to 10V input voltage range and supports an output voltage up to 40V.
Packaged in a compact 10-pin 2.5mm x 2.5mm MLF® package, the MIC2297-15YML-TR is suitable for space-constrained applications. It operates within a junction temperature range of -40°C to +125°C. Its features include PWM brightness control, DAC brightness control, low shutdown current, over-temperature protection, and UVLO.
Applications for this LED driver include PDAs, GPS systems, smartphones, mini PCs, digital cameras, IP phones, and LED flashlights. The surface mountable design and small package size make it ideal for portable electronic devices.
