■Cautions
・Connect the power supply terminals (VDD1 pin and VDD2 pin) with the shortest distance and set terminals same potential.
・Connect the grounding terminals (PGND pin, SWGND pin, AGND pin, and LEDGND pin)
・Connect the LX terminals (LX1 pin, LX2 pin) with the shortest distance and set terminals same potential.
・Connect the CS terminals (CS1 pin, CS2 pin, and CSS pin) with the shortest distance and set terminals same potential.
・It is recommended to install a capacitor between the power supply terminal and grounding terminal.
・Position a bypass capacitor between the power supply terminal and grounding terminal close to the IC and use broad patterns.
・It is recommended to install an approximately 1000-pF capacitor between the Power supply terminal and ENx pin for
・Use a broad and short patterns for the line that is connected from CVIN GND to CVIN GND through L and RCS.
・Position the Schottky-barrier diode (SBD) close to the CVOUT.
・Use patterns as broad and as short as possible for the power supply lines and grounding lines.
・Don’t set input terminals (ENR pin, ENG pin, ENB pin, STRIG pin, SDA pin, SCL pin, ADD0 pin, and ADD1pin)
・Apply the voltage to input terminals (ENR pin, ENG pin, ENB pin, STRIG pin, SDA pin, SCL pin, ADD0 pin, and
・In any cases including the timing of power on and power off, do not use absolute maximum ratings.
・Continuous running with the maximum output power may be caused exceeding maximum power dissipation. Be
・Position the RIREF close to the IC to circumvent the effect of noise.
