1 / 16 page  www.SiliconStandard.com 1 of 16 High efficiency boost converter Output current up to 500mA No external diode required PRODUCT SUMMARY DESCRIPTION High-efficiency Synchronous Step-up DC/DC Converter SS6610/11G 4/21/2006 Rev.3.01 Quiescent supply current of 20 mA. Power-saving shutdown mode (0.1 µA typical). Internal synchronous rectifier On-chip low-battery detector. Low battery hysteresis APPLICATIONS Palmtop and notebook computers. PDAs Wireless phones Pocket organizers. Digital cameras. Hand-held devices with 1 to 3 cells of NiMH/NiCd batteries. The SS6610/11G are high-efficiency step-up DC/DC converters, with a start-up voltage as low as 0.8V, and an operating voltage down to 0.7V. Consuming only 20 µA of quiescent current, these devices include a built-in synchronous rec- tifier that reduces size and cost by eliminating the need for an external Schottky diode, and improves overall efficiency by minimizing losses. The switching frequency can range up to 500KHz depending on the load and input volt- age. The output voltage can be easily set by: 1) two external resistors for 1.8V to 5.5V; 2) connecting FB to OUT to get 3.3V; or 3) connecting FB to GND to get 5.0V. The peak current of the internal switch is fixed at 1A (SS6610G) or 0.65A (SS6611G) for design flexibility. TYPICAL APPLICATION CIRCUIT Output 3.3V, 5.0V or adjustable from 1.8V to 5.5V up to 300mA output Low-battery Detect Out SS6610G SS6611G OUT FB GND REF LBO SHDN LX LBI + ON OFF + Low Battery Detection 0.1 µF VIN 22 µH 47 µF 47 µF Pb-free, RoHS compliant MSOP-8 FEATURES |
