Add To BomMAX668EUB+ General Description
The MAX668/MAX669 constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controllers are designed for a wide range of DC-DC conversion applications including step-up, SEPIC, flyback, and isolated-output configurations. Power levels of 20W or more can be controlled with conversion efficiencies of over 90%. The 1.8V to 28V input voltage range supports a wide range of battery and AC-powered inputs. An advanced BiCMOS design features low operating current (220µA), adjustable operating frequency (100kHz to 500kHz), soft-start, and a SYNC input allowing the MAX668/MAX669 oscillator to be locked to an external clock.
Features
- 1.8V Minimum Start-Up Voltage (MAX669)
- Wide Input Voltage Range (1.8V to 28V)
- Tiny 10-Pin µMAX Package
- Current-Mode PWM and Idle Mode Operation
- Efficiency Over 90%
- Adjustable 100kHz to 500kHz Oscillator or SYNC Input
- 220µA Quiescent Current
- Logic-Level Shutdown
- Soft-Start
Application
- Cellular Telephones
- LANs and Network Systems
- POS Systems
- Telecom Hardware
