Product Details

Description



Features:

• Operating supply voltage range: 1.5 V to 7.2 V
• High precision reference voltage circuit built-in (±1%)
• All channels are synchronous operation in PWM control
• Synchronous rectification for the low output voltage channel (Synchronous rectification can be stopped by the external signal at the low load: STOP)
• ON/OFF (sequence control) pin attached for each and all channels. Soft-start pins for each channel (Simultaneous soft start is available with one external capacitor.)
• Timer latch circuit for short-circuit protection circuit (Selectable for each channel separately or all channels simultaneously)
• Control frequency reduction is available by an external signal at the low load.
• Maximum duty cycle 88% (Adjustment range of 0% to 100% with an external resistor)
• Low power dissipation and high speed operation thanks to 0.6 m CMOS process


Application

• Digital still cameras

Note) *1: Except for the power dissipation, operating ambient temperature and storage temperature, all ratings are for Ta = 25°C.
*2: Ta = 85°C. For the independent IC without a heat sink. Note that applications must observe the derating curve for the relationship between the IC power consumption and the ambient temperature.
*3: Do not apply external currents or voltages to any pins not specifically mentioned. For the circuit currents, '+' denotes current flowing into the IC, and '−' denotes current flowing out of the IC.
*4: t < 10 ms, VDS < 5 V
