Mingjiada Electronics Supply ADI ADP5033 Series Dual Channel Buck Regulators

As the demands for precision and efficiency in power management continue to rise across portable electronic devices, industrial control systems and communications infrastructure, dual-channel step-down regulators have become key components in power supply architectures due to their high integration, small board footprint and design flexibility. Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier of the ADI (Analog Devices) ADP5033 series of dual-channel step-down regulators — provides reliable component support for a wide range of power supply designs.

[ADI] ADP5033 – Dual-channel, 3 MHz, 800 mA step-down regulator with two integrated 300 mA LDOs
Product Details:
The ADP5033 integrates two high-performance step-down regulators and two low-dropout regulators (LDOs) within a compact 16-pin 2 mm × 2 mm WLCSP package, meeting stringent performance and board space requirements.
The ADP5033’s LDOs feature low quiescent current, low dropout voltage and a wide input voltage range, extending battery life in portable devices. At frequencies up to 10 kHz, the ADP5033’s LDOs maintain power supply rejection ratio (PSRR) of over 60 dB whilst requiring minimal voltage margin.
The regulators in the ADP5033 are activated via the ENA and ENB pins. The specific channel controlled by ENA and ENB is factory-programmed. Applying a high level to the enable pins activates the regulators. The default output voltage can be factory-programmed from a wide range of options.
