XC9235/XC9236/XC9237
Series
600mA Driver Tr. Built-In, Synchronous Step-Down DC/DC Converters
ETR0514-016
The XC9235/XC9236/XC9237 series is a group of synchronous-rectification type DC/DC converters with a built-in
0.42Ω
P-
channel MOS driver transistor and 0.52Ω
N-channel MOS switching transistor, designed to allow the use of ceramic capacitors.
Operating voltage range is from 2.0V to 6.0V (A~C types), 1.8V to 6.0V (D~G types). For the D/F types which have a reference
voltage of 0.8V (accuracy:±2.0%), the output voltage can be set from 0.9V by using two external resistors. The A/B/C/E/G types
have a fixed output voltage from 0.8V to 4.0V in increments of 0.05V (accuracy:±2.0%). The device provides a high efficiency,
stable power supply with an output current of 600mA to be configured using only a coil and two capacitors connected externally.
With the built-in oscillator, either 1.2MHz or 3.0MHz can be selected for suiting to your particular application. As for operation
mode, the XC9235 series is PWM control, the XC9236 series is automatic PWM/PFM switching control and the XC9237 series
can be manually switched between the PWM control mode and the automatic PWM/PFM switching control mode, allowing fast
response, low ripple and high efficiency over the full range of loads (from light load to heavy load).
The soft start and current control functions are internally optimized. During stand-by, all circuits are shutdown to reduce current
consumption to as low as 1.0μA or less. The B/F/G types have a high speed soft-start
as fast as 0.25ms in typical for quick turn-
on. With the built-in UVLO function, the internal P-channel MOS driver transistor is forced OFF when input voltage becomes 1.4V
or lower.
The B to G types integrate C
L
discharge function which enables the electric charge at the output capacitor C
L
to be discharged
via the internal discharge switch located between the L
X
and V
SS
pins. When the devices enter stand-by mode, output voltage
quickly returns to the V
SS
level as a result of this function.
Four types of package SOT-25, USP-6C, USP-6EL and WLP-5-03 are available.
