MAS9251 产品详情

[MAS-Oy]

DESCRIPTION
MAS9251 is a low noise, constant frequency switched capacitor voltage doubler with regulated output. In the adjustable output version an external feedback pin allows the output voltage to be adjusted.
The high switching frequency of MAS9251 guarantees low output ripple even with small ceramic capacitors. The shutdown control pin can be used to turn off the device for power saving. MAS9251 is equipped with soft-start feature, which reduces the circuit’s disturbance to power supply lines during start-up by limiting the maximum input current.

FEATURES
• Two versions:
    Adjustable Output
    Fixed 5 V Output
• Solution without Inductors
• Soft-Start
• Output Accuracy < ± 4%
• Low External Part Count
• Low Noise
• Input Voltage Range: 2.7 V… 4.5 V
• Shutdown Control
• 1 MHz Switching Frequency
• Internal Thermal Shutdown
• Short Circuit Protection
• MSOP-8 and CSP Packages

APPLICATIONS
• LED Backlighting
• White LED Driver
• LED Brightness Control
• Li-Ion Battery Backup Supplies
• Local 3 V to 5 V Conversion
• Smart Card Readers
• PCMCIA Local 5 V Supplies
