ISL91302BIIZ-T集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

特性 Features

• Dual output 3+1 or 2+2, or single output 4-phase

• 2.5V to 5.5V supply voltage

• 5A per phase output current capability

• Small solution size

• High efficiency (94.7 peak for 3.8V VIN, 1.8V

VOUT, L = 470nH)

• Low IQ in low power mode

• Proprietary control scheme reduces the output

capacitor and supports fast load transients (such as

50A/μs per phase)

• Voltage, current, and temperature telemetry through

integrated ADC plus auxiliary inputs

• ±0.7 system accuracy with remote voltage sensing

• OTP programmable PWM frequency from 2MHz to

6MHz

• I2C and SPI programmable output from 0.3V to 2.0V

• Independent Dynamic Voltage Scaling (DVS) for

each output

• Soft-start and fault detection (UV, OV, OC, OT),

short-circuit protection

• 2.551mmx 3.670mm 54 ball WLCSP with 0.4mm pin

pitch
