XC9235/XC9236/XC9237

Series

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

ETR0514-009

The XC9235/XC9236/XC9237 series is a group of synchronous-rectification type DC/DC converters with a built-in 0.42Ω

P-channel driver transistor and 0.52ΩN-channel 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, ether 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 driver transistor is forced OFF when

input voltage becomes 1.4V or lower.

The B to G types integrate C

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

to be

discharged via the internal auto-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.

Two types of package SOT-25 (A/B/C types only) and USP-6C are available.
