Product Specification

IXD3235/36/37

Synchronous 600 mA Step-Down DC/DC Converter

Operating voltage range is from 2.0 V to 6.0 V (A ～

FEATURES

C types) or 1.8 V to 6.0 V (D ～ G types). For the D/F

types, which have a reference voltage of 0.8 V with ±

2.0% accuracy, the output voltage can be set from

0.9 V by using two external resistors.



Built-in transistors

Operating Input Voltage Range: 2.0 V ~ 6.0 V

(A/B/C types) or 1.8 V ~ 6.0 V (D/E/F/G types)



Output Voltage Range Externally Set: 0.8 V ~ 4.0

V (internally set) or 0.9 ~ 6.0 V (externally set)

The A/B/C/E/G types have a fixed output voltage

from 0.8 V to 4.0 V in increments of 0.05 V with

± 2.0% accuracy. The device requires only an

inductor and two externally connected ceramic

capacitors. The built-in oscillator, either 1.2 MHz or

3.0 MHz, can be selected.



Output Current: 600 mA

High Efficiency: 92%

Oscillation Frequency: 1.2 MHz, 3 MHz

Maximum Duty Cycle: 100%

The IXD3235 operates in PWM mode, the IXD3236

automatically switches between PWM/PFM modes,

and the IXD3237 allows switch manually between the

PWM and the automatic PWM/PFM switching control

modes. This allows fast response, low ripple, and

high efficiency over the full range of loads from light

to heavy.

Operating Modes: PWM, PWM/PFM auto select

or PWM/PFM manual select



Functions: Build-in Current Limit, Load Capacitor

Discharge, High Speed Soft start

Operating Ambient temperature: -40 ~ +85⁰C

Packages: SOT-25, USP-6C, USP-6EL, WLP-5-03

EU RoHS Compliant, Pb Free



The soft start and current control functions are

internally optimized. All circuits are disabled in a

standby mode to reduce current consumption to less

than 1.0 μA.

APPLICATION



Mobile Phones

Bluetooth headsets

Digital home appliances

Office automation equipment

Various portable equipment

The B/F/G types have a 0.25 ms high-speed soft-

start for quick turn-on. The built-in Under Voltage

Lockout (UVLO) function forces the internal

P-channel transistor OFF, when input voltage

becomes 1.4 V or lower.

DESCRIPTION

The B to G types have the output capacitor C_L

discharge circuitry, which allows fast C_Ldischarge

when IC goes into standby mode.

The IXD3235/36/37 series is a group of synchronous-

rectification type DC/DC converters with a built-in

0.52 Ω N-channel synchronous rectification transistor

and 0.42 Ω P-channel switching transistor providing

up to 600 mA output current.

Device is available in four types of packages: SOT-

25, USP-6C, USP-6EL, and WLP-5-03.
