GENERAL DESCRIPTION
XC9213 series is Nch-Nch drive, synchronous, step-down DC/DC
controller ICs with a built-in bootstrap driver circuit. Output will be
stable no matter which load capacitors, including a low ESR
capacitor, are used.
Resistance (RSENSE) of about 100m
will be required as a current
sense. The phase compensation is also run when a low ESR
capacitor is used. In addition, the circuit is double protected by the
ways of limiting the current while detecting overshoot current and
making output shutdown at any given timing by a protection time
setting capacitor (CPRO).
The output voltage can be set freely within a range of 1.5V~15.0V
with 1.0V (accuracy
±
1.5%) of internal reference voltage by using
externally connected resistors (RFB1, 2). Synchronous rectification
PWM control can be switched to non-synchronous 30mV current
limit PFM/PWM automatic switchable control (= voltage between
RSENSE pins) by using the MODE pin.
The series has a built-in voltage detector for monitoring a selected
voltage by external resistors.
During stand-by (CE pin = low) all circuits are shutdown to reduce
current consumption to as low as 3.0
μ
A or less.
