TA8161F DC / DC Converter System IC For Power Supply
The TA8161F is a DC / DC converter system IC, which is
developed for supplying a voltage (for 2.5V or 5V) for CMOS IC
etc.
It is especially suitable for low voltage operation, and for power
supply and back−up of speech recording / playback LSls, with
only one or two dry batteries.
Features Output voltage can be switched over to 2.5V or 5V
VO = 2.5V mode (by one dry−battery)
VO = 5V mode (by one or two dry−batteries) Built−in backup mode with a very low power dissipation
VCC = 1.2V, Ta = 25°C, IO = 0
ICC1 = 50µA (typ.)..... VO = 5V mode
ICC2 = 30µA (typ.)..... VO = 2.5V mode Built−in mode switch (back up mode / power supply mode) Excellent power efficiency, by blocking oscillation Output current (VCC = 1.2V, Ta = 25°C)
IO1 = 11mA (typ.)....... VO = 5V mode
IO2 = 22mA (typ.)....... VO = 2.5V mode Operating supply voltage range (Ta = 25°C)
VCC2 (opr) = 0.9~4V (VO = 5V mode)
VCC1 (opr) = 0.9~2.2V (VO = 2.5V mode)
