■GENERAL DESCRIPTION

■FEATURES

The

XC9235/9236/9237

series

group

P-Ch Driver Tr. Built-In

N-Ch Synchronous Driver

Tr. built-in

: ON resistance 0.42Ω

: ON resistance 0.52Ω

synchronous-rectification type DC/DC converters with a

built-in 0.42 Ω P-channel driver transistor and 0.52 Ω

N-channel switching transistor, designed to allow the use of

ceramic capacitors. The ICs enable a high efficiency, stable

power supply with an output current of 600mA to be

configured using only a coil and two capacitors connected

externally. Operating voltage range is from 1.8V to 6.0V.

Output voltage is internally programmable in a range from

0.8V to 4.0V in increments of 50mV <accuracy: ±1.5%(±

2.0%)>. With the built-in oscillator, oscillation frequency is

selectable from 600kHz, 1.2MHz, and 3.0MHz to make

available the frequency best suited 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 load (from

light load to high output current conditions).

Packages

Soft-Start Circuit Built-In

Current Limiter Circuit Built-In (Constant Current & Latching)

Low ESR Ceramic Capacitor Compatible

* Performance depends on external components

and wiring on the PCB.

The soft start and current control functions are internally

optimized. During standby, all circuits are shutdown to

reduce current consumption to as low as 1.0μA or less.

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 1.4V or lower.

Two types of

package, SOT-25 (250mW) and USP-6C (100mW), are

available.
