RT5028C

Integrated PMIC with 4-Channel Synchronous Buck

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

Industrial Applications

General Description

Features

^zInput Voltage Operating Range is 3.3V to 5.5V

^zStep-Down Regulator : V_INRange is 3.3V to 5.5V

` Max Current 2.4A/2A/1.6A/2A

The RT5028C 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

or Auto PSM/PWM)

The RT5028C includes four synchronous step-downDC-

DC converters and eight LDOs for system power.

The RT5028C also embeds one EEPROM (MTP) for

setting sequence and timing etc.

` I²C Programmable Output Discharge Mode

(Discharge or Flatting)

Additionally, the RT5028C PMIC also includes one IRQ

report.

z Linear Regulators : V_INRange is 2.5V to 5.5V

` Max Current 0.3A

` I²C Programmable Output Level

z Embedded 32Bytes MTP for Factory Tuning

` External MTP Pin for Write Protection

z Sequence can be Controlled by I²C or each EN pins

Defined by MASK_GPIO pin.
