TC1044SEPA

The TC1044SEPA is a kind of charge pump DC-to-DC voltage converter. It converts a +1.5 V to +12 V input to a corresponding -1.5 V to -12 V output. It is available in 8-Pin CerDIP package.

There are some features of TC1044SEPA as follows: (1) converts +5 V logic supply to ±5 V system; (2) wide input voltage range: 1.5 to 12 V; (3) efficient voltage conversion: 99.9%; (4) excellent power efficiency: 98%; (5) low power consumption: 80A @ VIN=5 V; (6) low cost and easy to use: only two external capacitors required; (7) RS-232 negative power supply; (8) improved ESD protection: up to 10 kV; (9) no external diode required for high voltage operation; (10) frequency boost raises FOSC to 45 kHz.

What comes next is about the maximum ratings of TC1044SEPA. (1): supply voltage is +13 V; (2): LV, Boost and OSC inputs voltage is from -0.3 to (V+ + 0.3) V for V+ < 5.5 V and (V+ - 5.5) to (V+ + 0.3) for V+ > 5.5 V; (3): current into LV is 20A for V+ > 3.5 V; (4): output short duration (VSUPPLY 5.5 V) is continuous; (5): lead temperature (soldering, 10 sec) is +300; (6): package power dissipation (TA 70) is 800 mW; (7): operating temperature range is from -40 to +85; (8): storage temperature range is from -65 to 150.
