2-Cell/ 500mA/ Step-Up DC/DC Converter

AIC1631 2-Cell, 500mA, Step-Up DC/DC Converter FEATURES High Efficiency 90%. Adjustable Output Voltage with Two Resistors (AIC1631A) Power-Saving Shutdown Mode (7µA typical). Internal 2A Switch. 120KHz Switching Rate. Adjustable Switch Current Limit. On-Chip Low Battery Detector. DESCRIPTION The AIC1631 is a high efficiency step up DCDC converter. Only four external components are required to deliver a fixed voltage of 3V, 3.3V, or 5V. The output voltage can be externally set to an arbitrary value below breakdown voltage of the power switch for AIC1631A. Efficiency beyond 87% can be easily achieved at 100mA load with 2.2V to 3V input voltages. APPLICATIONS Palmtop & Notebook Computers. Pocket Organizers. Cameras. Pagers. Battery Backup Supplies. Portable Instruments. Logic-controlled shutdown mode is provided for power saving. Switch current limit can be programmed with a resistor. The low battery detector can be configured as a linear regulator or a burst mode controller performing an extremely low supply current operation. 120KHz switching rate reduces the inductor size. Inductors of 25µH to 50µH inductance are commended for most applications. re- TYPICAL APPLICATION CIRCUIT +VIN L 1N5819 D1 +VOUT (3.3V) + C2 100µF Note: VIN≥1.8V, VOUT≤7V 100Ω R1 50µH + NORMAL C1 100µF RILIM ILIM/SD VIN SW SGND VOUT LBI LBO CGND SD LOAD AIC1631 High Efficiency Step-Up DC/DC Converter Analog Integrations Corporation DS-1631-04 Dec 27, 00 4F, 9, Industry E. 9th Rd, Science Based I.
