Overview
APW7215 Fixed 600kHz Step-UP Converter for White LEDs Features General Description • Wide Input Voltage from 2.
7V to 6V • Fixed 600kHz Switching Frequency • Reference Voltage : 0.
2V • PWM brightness control with wide frequency range of 5KHz to 100KHz • Build-in Power MOSFET: 0.
3Ω • Over-Voltage Protection • Under Voltage Lockout Protection • Over Temperature Protection • <1µA Quiescent Current during Shutdown • TDFN2x2-6 Package • Halogen and Lead Free Available (RoHS Compliant) Applications Th e APW72 15 is a current-mod e and fixed freq uen cy 600kHz boost converter with an integrated N-FET to drive white LEDs.
The series connection allows the LED current to be identical for uniform brightness.
Its low on-resistance of NFET and low feedback voltage reduce power loss and achieve high efficiency.
600kHz Constant switching frequency allows using small-size inductor and both ofinput and output capacitors.
An over voltage protection function, which m onitors the output voltage via LX pin, s tops s witching of the IC if the LXvoltage exceeds the over voltage threshold.
An internal soft-start circuit eliminates the inrush current during start-up.
The APW7215 also integrates under-voltage lockout and over-temperature protection to protect the IC in abnormal co ndi ti ons .
The APW72 15 is avai lab le in TD FN2 x2 -6 package.
