STOD30

300 mA triple DC-DC converter for powering AMOLED display

Data brief

• Temperature range -40 °C to 85 °C

• True shutdown mode

• Fast outputs discharge after shutdown

• Short-circuit protection

• Package QFN 3.5x3.5 18 leads, 0.5 mm pitch

Applications

QFN18 3.5x3.5 mm

• Active matrix OLED power supply in portable

devices

Features

• Cellular phones, multimedia players,

camcorders and digital cameras

• Two step-up converters and an inverting

converter

Description

• Operating input voltage range from 2.5 V to

4.5 V

The STOD30 is a triple DC-DC converter for

AMOLED display panel. It integrates 300 mA

step-up and inverting DC-DC converters plus

auxiliary step-up converter. This device is

particularly suitable for battery operated products,

in which the major concern is the overall system

efficiency. It works in pulse skipping mode during

low load condition and PWM mode at 1.45 MHz

frequency for medium/high load conditions. The

high frequency allows the value and size of

external components to be reduced. The enable

and SWIRE pins allow the device to be turned off

so to reduce the current consumption to less than

1 μA. The negative inverter and auxiliary step-up

positive output voltages can be programmed by

an MCU through a dedicated pin which

• Synchronous rectification for all DC-DC

converters

• 300 mA output current for step-up and inverting

converters (V_IN> 2.9 V)

• 60 mA output current for auxiliary step-up

converter

• Step-up converter fixed 4.6 V positive voltage

• Programmable negative voltage by S_WIREfrom

-1.4 V to -5.4 V in 100m V steps

• Greater than 90% efficiency

• Pulse skipping mode at light load condition

• 1.45 MHz PWM mode control switching

frequency

implements S_WIREprotocol. Auxiliary step-up

positive output voltage is also configured by an

external pull-down resistor. Soft-start with

controlled inrush current limit, thermal shutdown

and short-circuit protection are integrated

functions of the device.

• TDMA noise high immunity

• Auxiliary step-up converter positive voltage

programmable by S_WIREfrom 6.7 V to 7.6 V in

300 mV steps and configurable by external

pull-down resistor

• Enable pin for auxiliary step-up converter

shutdown mode

Table 1. Device summary

• Low quiescent current in shutdown mode

• Soft-start with inrush current protection

• Overtemperature protection
