Description
Traduction par IA
The MAX887 is a step-down, pulse-width modulation (PWM) DC-DC converter that provides an adjustable output from 1.25V to 10.5V. It accepts inputs from 3.5V to 11V and delivers up to 600mA. An internal MOSFET and synchronous rectifier reduce PC board area while maintaining high efficiency. Cycle-by-cycle current limiting protects the internal MOSFETs and reduces system stress during overload conditions. Operation with up to 100% duty cycle for an output of 3V and higher minimizes dropout voltage. Fixed-frequency PWM operation reduces interference in sensitive communications and data-acquisition applications. A SYNC input allows synchronization to an external clock. When enabled, Idle Mode™ extends battery life.

- The MAX887 high-efficiency, step-down DC-DC converter provides an adjustable output from 1.25V to 10.5V.
- It accepts inputs from 3.5V to 11V and delivers 600mA.
- Operation to 100% duty cycle minimizes dropout voltage (300mV typ at 500mA).
- Synchronous rectification reduces output rectifier losses, resulting in efficiency as high as 95%.
- Fixed-frequency pulse-width modulation (PWM) reduces noise in sensitive communications applications.
- Using a high-frequency internal oscillator allows tiny surface-mount components to reduce PC board area, and eliminates audio-frequency interference.
- A SYNC input allows synchronization to an external clock to avoid interference with sensitive RF and data-acquisition circuits.
- The MAX887 features current-mode operation for superior load/line-transient response.
- Cycle-by-cycle current limiting protects the internal MOSFET and rectifier.
- A low-current (2.5μA typ) shutdown mode conserves battery life.
