1 / 10 page UNISONIC TECHNOLOGIES CO., LTD UC3550 CMOS IC www.unisonic.com.tw 1 of 10 Copyright © 2005 Unisonic Technologies Co., Ltd QW-R502-082,A PWM CONTROLLED, PWM/PFM SWITCHABLE STEP-UP DC-DC CONTROLLER DESCRIPTION The UTC UC3550 series is a compact, high efficiency, step-up DC/DC controllers includes an error amplifier, oscillator, PWM comparator, skip cycle comparator, voltage reference, soft-start, and high speed lower ON-resistance driver for driving external power devices (NMOS or NPN) ,Additionally, a CE (chip enable) function that reduces power consumption during shut-down mode. That typically operated from a single-or dual-cell battery packs. It have a driver pin ,ext pin, for connecting to an external transistor ( NMOS or NPN). a lower ON-resistance external transistor can obtain larger output current. With only external components, this series allow a simple means to accommodate high output current applications. The UTC UC3550 series goes automatically into skip switching cycles under light load condition to maintain high efficiency. FEATURES * Input voltage range:0.9~8V * Output voltage range:1.8~6V programmable in 0.1V with high accuracy ± 2.5% * High efficiency 88%(typ.) * Low start-up voltage of 0.9V typical at IOUT = 1.0mA * Oscillator frequency: 300kHz.(±20%) * Chip enable pin with pull-up current source * High output current up to 1000mA (VIN = 2.0V, VOUT =3.3V) SOT-25 4 5 3 2 1 *Pb-free plating product number: UC3550L ORDERING INFORMATION Order Number Normal Lead Free Plating Package Packing UC3550-xx-AF5-R UC3550L-xx-AF5-R SOT-25 Tape Reel UC3550L-xx-AF5-R (1)Packing Type (2)Package Type (4)Lead Plating (1) R: Tape Reel (2) AF5: SOT-25 (4) L: Lead Free Plating, Blank: Pb/Sn (3) xx: reference to Marking Information (3)Voltage Code |
