The ZXSC400 is voltage mode boost converter in SOT23-6 package. Its low feedback voltage allows the current in a chain of LEDs to be set and accurately monitored with a single resistor with minimal losses.
The ZXSC400EV4 is configured as a boost converter to drive a 1W LED from two NiCd / NiMH batteries.
