MAX1630
Key Features
- Up to 96% efficiency is achieved through synchronous rectification and Maxim’s proprietary Idle Mode™ control scheme
- Efficiency is greater than 80% over a 1000:1 load-current range, which extends battery life in systemsuspend or standby mode
- Excellent dynamic response corrects output load transients caused by the latest dynamic-clock CPUs within five 300kHz clock cycles
- Strong 1A on-board gate drivers ensure fast external N-channel MOSFET switching
- These devices feature a logic-controlled and synchronizable, fixed-frequency, pulse-width-modulation (PWM) operating mode
- This reduces noise and RF interference in sensitive mobile munications and pen-entry applications
- Asserting the SKIP pin enables fixed-frequency mode, for lowest noise under all load conditions
- The MAX1630–MAX1635 include two PWM regulators, adjustable from 2.5V to 5.5V with fixed 5.0V and 3.3V modes
- All these devices include secondary feedback regulation, and the MAX1630/MAX1632/MAX1633/ MAX1635 each contain 12V/120mA linear regulators
- The MAX1630/MAX1631/MAX1632 contain internal output overvoltage and undervoltage protection features
