1 / 8 page TS1910 680kHz/1.2MHz High Voltage Boost Converter 1/8 Version: A12 SOP-8EP General Description The TS1910 is a high performance, high efficiency step up DC-DC Converter with integrated 2A. The TS1910 converter input voltage ranging from 2.6 to 5.5V. The Output voltage can be set up to 27V. The selectable frequency of 680kHz and 1.2MHz allows the use of small external inductors and capacitors and provides fast transient response. Current mode control with external compensation network makes it easy to stabilize the system and keep maximum flexibility. Programmable soft start function minimizes impact on the input power system. Internal power MOSFET with very low RDS(ON) provides high efficiency. The TS1910 automatically transits from PWM to PFM during light load condition further increasing efficiency. The converter also provides protection functions such as Current Limit and Thermal shutdown. Features ● 2.6V to 5.5V operating input voltage range ● Adjustable output voltage range up to 27V ● Up to 2A output switch current ● 680K/1.2MHz Selectable Switching Frequency ● Programmable soft-start function ● External Compensation Network ● Current limit and Thermal shutdown protection ● Under voltage Lockout ● ≤1µA Shutdown Current Application ● Digital Still Cameras ● Portable Electronics ● PDA’s and Palm-Top Computers ● Local Boost Regulator Ordering Information Part No. Package Packing TS1910CS RLG SOP-8EP 2.5Kpcs / 13” Reel Note: “G” denotes for Halogen Free Absolute Maximum Rating Parameter Symbol Limit Unit VCC Pin Voltage VCC GND - 0.3 to GND + 6 V EN, FREQ,COMP,FB,SS, Pin Voltage GND - 0.3 to VCC + 0.3 V LX Pin Voltage VLX 30 V Power Dissipation PD ( TJ-TA ) / θJA mW Storage Temperature Range TST -65 to +150 °C Operating Junction Temperature Range TOP -40 to +125 °C Thermal Resistance from Junction to case θJC 15 °C/W Thermal Resistance from Junction to ambient θJA 40 °C/W Note: θJA is measured with the PCB copper area of approximately 1.5 in2(Multi-layer). That copper area needs connect to exposed pad. Pin Definition: 1. COMP 8. SS 2. FB 7. FREQ 3. EN 6. VCC 4. GND 5. LX |
