LP8758-EA
- Fully integrated quad buck, up to 4-A programmable maximum output current per buck
- Auto PWM-PFM and forced-PWM operations
- Programmable output voltage slew rate from 30 mV/µs to 0.5 mV/µs
- Input voltage range: 2.5 V to 5.5 V
- VOUT range: 0.5 V to 3.36 V with DVS
- Programmable start-up and shutdown sequencing with enable signal
- I2C-compatible interface that supports standard (100 kHz), fast (400 kHz), fast+ (1 MHz), and high-speed (3.4 MHz) modes
- Interrupt function with programmable masking
- Load current measurement
- Output short-circuit and overload protection
- Spread-spectrum mode for EMI reduction
- The four buck cores operate 90° out of phase thereby reducing input ripple current
- Overtemperature warning and protection
- Undervoltage Lockout (UVLO)
The LP8758-EA device is designed to meet power management requirements for low-power processors in mobile phones, network cards, and similar applications. The device contains four step-down DC-DC converter cores, providing four output voltage rails. The device is controlled by an I2C-compatible serial interface.
The automatic PWM-PFM (AUTO mode) operation maximizes efficiency over a wide output-current range.
The LP8758-EA supports programmable start-up and shutdown sequencing synchronized to hardware Enable input signal.
The protection features include short-circuit protection, current limits, input supply UVLO, and temperature warning and shutdown functions. Several error flags are provided for status information of the device. In addition, the LP8758-EA device supports load current measurement without the addition of external current sense resistors. During start-up and voltage change, the device controls the output slew rate to minimize output voltage overshoot and the inrush current.
