Characteristic
The XC6376/77 series are step-down DC/DC converters with built-in P-
channel power MOSFETs. A highly efficient DC/DC converter with output
currents of 500mA can be realised using only four peripherals - a coil, a
diode and 2 capacitors.
Output voltage can be internally set-up in 0.1V increments (±2.5%)
between 1.5V and 6.0V (VOUT type). Alternatively, output voltage can be
set-up at will using a 1.0V internal reference voltage source and
peripherals (FB type). It is possible to reduce the size of the peripherals
used since the switching frequency is 300kHz.
The PWM//PFM switchable XC6377 operates in PFM mode during light
loads and is highly efficient from light loads to large output currents.
Required values for soft start time can be regulated via the external
capacitor and the stand-by function reduces supply current to less than
2.5
µA.
U.V.L.O and protection are built-in.
