The Microchip 1.2 MHz pulse-width modulated step-up switching regulator is optimized for constant current white LED driving applications. With a switch current of over 350 mA, it drives a string of up to 4 white LEDs in series, ensuring uniform brightness and eliminating the need for multiple ballast resistors. The regulator uses a constant frequency 1.2 MHz PWM current-mode control scheme, which saves board space by reducing external component sizes. The constant frequency operation also results in much lower noise and input ripple injected back to the battery source, compared to variable frequency control schemes.
