The MAX887HESA is a high-efficiency, step-down DC-DC converter designed by Analog Devices (formerly Maxim Integrated). It offers an adjustable output voltage ranging from 1.25V to 10.5V and can deliver up to 600mA of output current. This converter operates with high efficiency, reaching up to 95%, and minimizes dropout voltage with 100% duty cycle operation. Its fixed-frequency pulse-width modulation (PWM) design reduces noise, making it suitable for sensitive communications applications. The internal oscillator operates at high frequencies, allowing for small surface-mount components and reducing PC board area.
The MAX887HESA features current-mode operation for superior load and line-transient response, along with cycle-by-cycle current limiting for internal MOSFET protection. A low-current shutdown mode conserves battery life, drawing only 2.5µA typically. The device accepts input voltages from 3.5V to 11V. It is available in an 8-pin SOIC package and is designed for surface mount applications.
Key features include 95% efficiency, 600mA output current, low-dropout operation, internal synchronous rectifier, and an internal 300kHz oscillator. An external SYNC input allows synchronization to an external clock to avoid interference with RF and data-acquisition circuits. Applications include portable instruments, cellular phones, personal communicators, distributed power systems, and computer peripherals.
