ST755
ST755 - Brand New IC DC Switching Regulators
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
DESCRIPTION
The ST755 is an adjustable inverting switch-mode DC-DC rergulator with internal Power MOSFET that generaters an adjustable negative output from a voltage input of 2.7V to 11V, output current guaranteed at 200mA (for Vin>4.5V, Vout = -5V and 0oC ≤ Ta ≤ 70oC) and 275mA (typical value at Ta = 25 oC, Vout = -5V). A logic controlled shut down pin that interfaces directly with microprocessor reduces supply current to only 10µA. Input to Output differential voltage is limited to Vin+|Vout|<12.7V. No load supply current is 1.2mA.
■ 2.7V TO 11V INPUT TO ADJUSTABLE NEGATIVE OUTPUT CONVERSION
■ 1W GUARANTEED OUTPUT POWER (Vin>4.5V, T≤70oC)
■ 68% TYP. EFFICENCY AT 6V
■ VERY LOW QUIESCENT CURRENT: 1.2mA IN ON MODE 10µA IN SHUT DOWN MODE
■ SOFT START
■ VERY LOW NOISE OUTPUT
■ 160KHz FIXED FREQUENCY OSCILLATOR MIXED BIPOLAR-CMOS TECHNOLOGY
