Description

The ST735 is a Bi-CMOS, inverting switch mode DC-DC regulator with internal Power MOSFET's that generates a fixed -5V output voltage from a 4V to 6.2V input voltage; is guaranteed an output current of 200mA for inputs greater than 4.5V. The quiescent current for this device is typically of 0.8mA and, in shutdown mode it is reduced to 10µA.

These power-conserving features, along with high efficiency and applications circuits, that lend itself to minaturization, make the ST735 excellent in a broad range of on-card, HDD and portable equipment applications. The ST735 employ a high performance current mode pulse with modulation (PWM) control scheme to provide tight output voltage regulation and low noise. The fixed frequency oscillator is factory trimmed to 160KHz, allowing for easy noise filtering. The regulator in production is tested to guarantee an output accuracy within ±5% over all specified conditions.
