RT5028E

Integrated PMIC with 4-Channel Synchronous Buck

Converters, 8 LDOs, and MTP Non-Volatile Memory for

Industrial Applications

General Description

Features

 Input Voltage Operating Range is 3.3V to 5.5V

 Step-Down Regulator : V_INRange is 3.3V to 5.5V

^Max Current 2.4A/2A/1.6A/2A

The RT5028E is a highly-integrated low-power high-

performance analog SOC with PMIC in one single chip

designed for industrial applications.

^Programmable Frequency from 500kHz to 2MHz

^I²C Programmable Output Level

^I²C Programmable Operation Mode (Force PWM

The RT5028E includes four synchronous step-downDC-

DC converters and eight LDOs for system power.

The RT5028E also embeds one EEPROM (MTP) for

setting sequence and timing etc.

or Auto PSM/PWM)

^I²C Programmable Output Discharge Mode

(Discharge or Flatting)

Additionally, the RT5028E PMIC also includes one IRQ

report.
