MAX1653EEE-T Description

Short technical summary and product information.

The MAX1653EEE-T is a high-efficiency, pulse-width-modulated (PWM) step-down DC-DC controller manufactured by Analog Devices (formerly Maxim Integrated). It is designed for applications requiring efficient voltage conversion.

 

Key electrical specifications include an input voltage range of 4.5V to 30V and selectable switching frequencies of 150kHz or 300kHz. The controller supports a maximum duty cycle of 98% and features synchronous rectification for improved efficiency. Control features include Enable and Soft Start.

 

This device is housed in a compact 16-QSOP package, suitable for surface mounting. The operating temperature range is -40°C to 85°C (TA). Its topology is a Buck regulator, configured for a positive output. The MAX1653EEE-T is designed for applications such as notebook computers, PDAs, and mobile communicators.

 

This controller utilizes an Idle Mode™ synchronous-rectified PWM control scheme to optimize efficiency across varying load conditions. It can automatically switch between PWM operation at heavy loads and pulse-frequency-modulated (PFM) operation at light loads. The MAX1653/MAX1655 also feature logic-controlled, forced PWM operation for noise-sensitive applications.
