Beschreibung
The EVQ7920-R-00A is an evaluation board designed to demonstrate the capabilities of the MPQ7920, a power management IC (PMIC) solution with four integrated, high efficiency, DC/DC step-down converters; five low-dropout (LDO) regulators; and a flexible I2C interface. Constant-on-time (COT) control provides fast transient response for the step-down converters. During continuous conduction mode (CCM), the adjustable switching frequency (fSW) (up to 2.75MHz) reduces the external inductance and capacitance.

- Buck 1: 4.5A DC/DC Converter
- Buck 2: 2.5A DC/DC Converter
- Buck 3: 4.5A DC/DC Converter
- Buck 4: 2A DC/DC Converter
- Buck 1 and Buck 3 Can Operate in Parallel
- Buck 2 and Buck 4 Can Operate in Parallel
- 2.7V to 5.5V Input Voltage (VIN) Range
- Buck 1, Buck 2, and Buck 3 VOUT:
- 0.4V to 2.2V/7.4mV Step
- 0.4V to 3.58V/12.5mV Step
- Buck 4 VOUT: 0.4V to 3.58V/12.5mV Step
- Configurable fSW, tSS, and Phase Delay
- Configurable Forced PWM (FPWM)
- Mode, Auto-PFM Mode, and Auto-PWM
- Output OCP and OVP
- Low-Dropout (LDO) Regulators:
- One RTC Dedicated LDO
- Four Low-Noise LDOs
- Two Separate Input Power Supplies
- 25mV Dropout Voltage at 150mA Load
- I2C Interface and Configurable MTP (1)
- Enable (EN) On/Off Control
- Multi-Function Pin (LDO2/EN1) (2)
- Start-Up Reset Output (RSTO)
- 0.5ms/2ms/8ms/16ms Flexible Start-Up Sequence via the MTP
- Flexible DC/DC LDO On/Off Control via the MTP
- ESD Ratings (All Pins): ±4kV HBM and ±2kV CDM
