STEP-UP, FOR LCD BIAS SUPPLY, 3-CHANNEL

SWITCHING REGULATOR

S-8335 Series

The S-8335 Series is a bias supply IC for a Multi Line Addressing (MLA)

driven LCD using a dual-line simultaneous selection mode. This IC

supports medium-sized LCD panels. Two step-up type and one inverter

type PFM control CMOS switching regulators supply the required positive

or negative power to the two MLA-driven LCD common drivers and

segment drivers. Because of its CMOS structure, the current consumption

of the S-8335 Series is extremely low, which makes it ideal for the LCD

power supply of portable equipment that requires low power consumption.

Also, an extremely low power consumption LCD module can be created by

using the S-8335 Series with the LCD common driver (HD66523R

∗

Manufactured by Hitachi, Ltd.) and segment driver (HD66522

∗

Manufactured by Hitachi, Ltd.).

∗

1:These drivers are able to support 1/240duty and 1/200duty.

Features

•

Supports four types of LCD panels (1/240 duty, 1/200 duty, 1/160 duty, and 1/120 duty).

•

Input voltage range: 2.4 to 5.0 V (The S-8335 can be driven by a single direct-coupled lithium battery.)

•

Output voltage range

Common driver positive power supply (VRH) output voltage range(typ.value)

8.91 to 16.59 V (S-8335A240FT)

8.22 to 15.30 V (S-8335A200FT)

7.48 to 13.93 V (S-8335A160FT)

6.66 to 12.41 V (S-8335A120FT)

(This supply can be varied by on-chip 6-bit electric volume. Power MOSFET is built in.)

Common driver negative power supply (VRL) output voltage range(typ.value)

-6.87 to -12.80 V (S-8335A240FT)

-6.18 to -11.49 V (S-8335A200FT)

-5.44 to -10.13 V (S-8335A160FT)

-4.61 to -8.59 V (S-8335A120FT)

Segment driver positive power supply (VCH) output voltage range 2.0 to 3.8 V

Segment driver intermediate potential (VM) output voltage range 1.0 to 1.9 V

Icon positive power supply (VICON) output voltage range 1.0 to 2.2 V (This supply can be set arbitrarily

by external resistors.)

•

Triple operation mode function: Triple mode switching according to 2-bit input

Mode 1: Normal operation

Mode 2: Icon mode (reference voltage circuit- and regulator S-only operation)

Mode 3: Standby mode (power off)

•

Power-off function

Stops step-up or step-down operation and short circuits VRH and VRL to VSS by on-chip and external

Nch transistors.

•

Soft-start function: This function can be set according to an external capacitor (CSS).

•

Oscillation frequency: 100 kHz

20 kHz, Duty = 50%

•

Lead-free products

Applications

•

Power supply for medium-sized LCD panel
