TC1121COA

The TC1121 is a charge pump converter with 100mA output current capability. It converts a 2.4V to 5.5V input to a corresponding negative output voltage. As with all charge pump converters, the TC1121 uses no inductors saving cost, size and EMI.The TC1121COA belongs to TC1121 series.

Features of the TC1121COA are:(1)optional high-frequency operation allows use of small capacitors;(2)low operating current (FC = GND);(3)high output current (100mA);(4)converts a 2.4V to 5.5V input voltage to a corresponding negative output voltage (inverter mode);(5)uses only 2 capacitors; no inductors required;(6)selectable oscillator frequency;(7)power-saving shutdown input;(8)available in 8-pin MSOP, 8-pin PDIP and 8-pin small outline (SOIC) packages.Applications of the TC1121COA are:(1)laptop computers;(2)medical instruments;(3)disk drives;(4)P-based controllers;(5)process instrumentation.

The absolute maximum ratings of the TC1121COA can be summarized as:(1):the parameter is supply voltage (VDD),the rating is 6,the unit is V;(2):the parameter is OSC, FC, SHDN input voltage,the rating is -0.3 to (V+ + 0.3),the unit is V;(3):the parameter is output short circuit duration,the rating is 10,the unit is sec;(4):the parameter is package power dissipation (TA 70) 8-Pin PDIP,the rating is 730,the unit is mW; (5):the parameter is package power dissipation (TA 70) 8-Pin SOIC,the rating is 470,the unit is mW;(6):the parameter is package power dissipation (TA 70) 8-Pin MSOP,the rating is 333,the unit is mW;(7):the parameter is operating temperature range C Suffix,the rating is 0 to +70,the unit is ;(8):the parameter is operating temperature range E Suffix,the rating is -40 to +85,the unit is ;(9):the parameter is storage temperature range C Suffix,the rating is -65 to +150,the unit is .
