XC9235/XC9236/XC9237

Series

600mA Driver Tr. Built-In, Synchronous Step-Down DC/DC Converters

ETR0514-011a

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 0.52ΩN-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 (Under Voltage Lock Out) 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

discharge function which enables the electric charge at the output capacitor C

to be discharged

via the internal discharge switch located between the L

and V

pins. When the devices enter stand-by mode, output voltage

quickly returns to the V

level as a result of this function.

Three types of package SOT-25 (A/B/C types only), USP-6C, and 0.4mm low height USP-6EL (A/B/C types only) are available.
