for low voltage
MB39A105
s DESCRIPTION
The MB39A105 is 1-channel DC/DC converter IC using pulse width modulation (PWM). This IC is ideal for up
conversion.
The minimum operating voltage is low (1.8 V) , and the MB39A105 is best for built-in power supply such as LCD
monitors. Also the short-circuit protection detection output function prevents input/output short on a chopper type
up-converter.
This product is covered by US Patent Number 6,147,477.
s FEATURES
• Power supply voltage range : 1.8 V to 6 V
• Reference voltage accuracy : ± 1 %
• High-frequency operation capability : 1 MHz (Max)
• Built-in standby function: 0 µA (Typ)
• Built-in timer-latch short-circuit protection circuit
• Built-in short-circuit protection detection output function
• Built-in soft-start circuit independent of loads
• Built-in totem-pole type output for Nch MOS FET
• Package : TSSOP-8P (Thickness 1.1 mm Max)
s PACKAGE
8-pin plastic TSSOP
