XC9510 Series
PWM, PWM / PFM Automatic
Switching External
The XC9510 series consists of a step-down DC/DC converter and a
high-speed LDO regulator connected in series with the DC/DC
converter's output. A voltage detector is also built-in. A highly
efficient, low noise output is possible since the regulator is stepped-
down further from the DC/DC output.
The DC/DC converter block incorporates a P-Channel driver transistor
and a synchronous N-Channel switching transistor. With an external
coil, diode and two capacitors, the XC9510 can deliver output currents
up to 800mA at efficiencies over 90%. The XC9510 is designed for
use with small ceramic capacitors.
A choice of three switching frequencies are available, 300 kHz, 600
kHz, and 1.2 MHz.
Output voltage settings for the DC/DC and VR are set-up internally in
0.1V steps within the range of 0.9V to 4.0V (
± 2.0%). For the VD, the
range is of 0.9V to 5.0V (
± 2.0%).
The soft start time of the series is internally set to 5ms. With the built-
in U.V.L.O. (Under Voltage Lock Out) function, the internal P-channel
driver transistor is forced OFF when input voltage becomes 1.4 V or
lower.
The operational states of the DC/DC and the regulator blocks can be
changed by inputting three kinds of voltage level via the CE/MODE pin.
The functions of the MODE pin can be selected via the external control
pin to switch the DC/DC control mode and the disable pin to shut down
the regulator block.
