DC DC Switching Controllers datasheet and documents for MAX1653EEE+T
DC DC Switching Controllers Overview
The MAX1653EEE+T is a high-efficiency, PWM step-down DC-DC switching controller manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an input voltage range of 2.7V to 5.5V and delivers an adjustable output voltage from 0.8V to 5.5V. The device supports a maximum switch current of 2A and functions at a fixed switching frequency of 500kHz. It is housed in a 16-pin QSOP package and is rated for operation between -40°C and +85°C.
DC DC Switching Controllers Feature Summary
- Integrates a power MOSFET with a synchronous rectifier for enhanced efficiency
- Features a fixed 500kHz switching frequency to minimize external component size
- Includes comprehensive protection mechanisms such as overcurrent and thermal shutdown
DC DC Switching Controllers Applications
- Portable battery-powered equipment
- Notebook computers
- Personal digital assistants (PDAs)
- Wireless communications systems
DC DC Switching Controllers Procurement Notes
Verify the specific suffix 'EEE+T' to confirm the QSOP-16 package and tape-and-reel delivery format. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm RoHS compliance status through official manufacturer documentation before integration into production designs.
DC DC Switching Controllers Selection Notes
Select this component when a compact, high-current buck solution is required for single-cell lithium-ion or nickel-based battery applications. The integrated synchronous design reduces the need for external Schottky diodes, saving board space. Verify that the load current requirements do not exceed the 2A internal switch limit.
DC DC Switching Controllers Part Context
This part belongs to the MAX1653 family of high-efficiency step-down controllers. It is designed specifically for applications requiring low quiescent current and high power density. The device simplifies design by integrating the control logic and power switches into a single small footprint.
DC DC Switching Controllers Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic replacements may differ in pinout, thermal performance, or control architecture.
