ACT6330 Rev0, 02-Apr-08 www.DataSheet4U.com Dual PWM Step-Up DC/DCs in TQFN33 FEATURES • Multiple Patents Pending • Two Integrated Regulators − PWM Step-Up DC/DC with OVP for WLED Bias − PWM Step-Up DC/DC Converter with OVP GENERAL DESCRIPTION The patent-pending ACT6330 integrates two stepup DC/DC into a single, thin, space-saving package to provide a cost-effective, highly-efficient ActivePMUTM power management solution. This device is ideal for a wide range of portable handheld equipment that can benefit from the advantages of ActivePMU technology but does not require a high level of integration. REG1 and REG2 are fixed-frequency, current mode PWM step-up DC/DC converter. REG1 is optimized for high-efficiency WLED bias applications. REG2 is optimized for voltage regulation applications, while together these output can provide a complete TFT bias and backlighting solution for portable handheld equipment. The ACT6330 is available in a tiny 3mm x 3mm 16 pin Thin-QFN package that is just 0.75mm thin. • Independent Enable/Disable Control • Minimal External Components • 3×3mm, Thin-QFN (TQFN33-16) Package − Only 0.75mm Height − RoHS Compliant APPLICATIONS • • • • Portable Devices and PDAs MP3/MP4 Players Wireless Handhelds GPS Receivers SYSTEM BLOCK DIAGRAM Battery REG1 Step-Up DC/DC System Control OUT1 WLED Bias Up to 18 LEDs ON1 ON2 Pb-free REG2 ACT6330 Active Step-Up DC/DC OUT2 Up to 20V PMU TM Innovative PowerTM ActivePMUTM is a trademark of Active-Semi. -1- www.active-semi.com Copyright © 2008 Active-Semi, Inc. www.DataSheet4U.com ACT6330 Rev0, 02-Apr-08 FUNCTIONAL BLOCK DIAGRAM ACT6330 IN UVLO To Battery SW1 OVP1 OUT1 ON1 REG1 FB1 GP12 ON2 SW2 OVP2 REG2 FB2 GP12 To Battery OUT2 GA Innovative PowerTM ActivePMUTM is a trademark of Active-Semi. -2- www.active-semi.com Copyright © 2008 Active-Semi, Inc. www.DataSheet4U.com ACT6330 Rev0, 02-Apr-08 ORDERING INFORMATION PART NUMBER ACT6330QK-T PACKAGE TQFN33-16 PINS 16 TEMPERATURE RANGE -40°C to +85°C All Active-Semi product are offered in lead-free RoHS Compliant packaging.

Connect GAs directly to a quiet ground node. Connect GAs and GP12 together at a single point as close to the IC as possible. Feedback Sense for REG1. Connect this pin to the LED string current sense resistor to sense the LED current. Over-Voltage Protection Input for REG1. Connect this pin directly to the output node to sense and prevent over-voltage conditions. Switching Node Output for REG1. Connect this pin to the switching end of the inductor. Power Ground for REG1, REG2. Connect GP12 directly to a power ground plane. Connect GAs and GP12 together at a single point as close to the IC as possible. Switching Node Output for REG2. Connect this pin to the switching end of the inductor. Over-Voltage Protection Input for REG2. Connect this pin directly to the output node to sense and prevent over-voltage conditions. Feedback Sense for REG2. Connect this pin to the center point of a resistive voltage divider to sense output voltage. Enable Control Input for REG2. Drive ON2 to IN or to a logic high for normal operation, drive to GA or a logic low to disable REG2. Enable Control Input for REG1. Drive ON1 to IN or to a logic high for normal operation, drive to GA or a logic low to disable REG1. Power Input for the IC. Bypass IN to GA with a capacitor placed as close as possible to the IC. Exposed Pad. Must be soldered to ground on the PCB.
