The MAX1653EEE is a high-efficiency, pulse-width-modulated (PWM) step-down DC-DC controller designed for various power management applications. It is housed in a compact 16-QSOP package, suitable for space-constrained designs.
This controller operates with an input voltage range of 4.5V to 30V, offering flexibility for different power sources. It supports selectable switching frequencies of 150kHz or 300kHz, allowing optimization for efficiency or component size. The device features a maximum duty cycle of 98% for improved dropout performance and a quiescent supply current of 170µA for better light-load efficiency. It also includes control features such as Enable and Soft Start.
The MAX1653EEE is designed for applications requiring efficient voltage regulation, such as notebook computers, PDAs, and mobile communicators. Its step-down topology and synchronous rectifier enable high efficiency, reaching up to 96% according to datasheet specifications. The surface mount package facilitates integration into printed circuit boards.
Key electrical characteristics include a 4.5V to 30V input voltage range, a 150kHz/300kHz switching frequency, and a 98% maximum duty cycle. The operating temperature range is -40°C to 85°C (TA). The device is RoHS3 compliant.
