ST755CN is a buck regulator with an integrated high voltage MOSFET in a small 3mm x 3mm WL-CSP_7 package. It is the ideal choice for low-power, cost-sensitive and size-constrained applications, such as medical and industrial control products, digital camera, and many other consumer and portable devices. This device offers 500 mA of continuous output current with a wide output voltage range of 1.2V to 5.0V and also offers high efficiency, low noise and fast transient response.

The ST755CN DC-DC buck regulator, despite its small package size, is able to support a wide range of input voltages, making it an ideal choice for point-of-load power applications. The device has a wide operating voltage range of 2.3V to 16V and can also run down to 0V with no power dissipation. With a low quiescent current of 1mA and integrated PFM/PWM mode uring light load, the device can operate efficiently over the full load range.

The ST755CN has built-in programmable soft-start, UVLO, short-circuit protection, and thermal shutdown features. It also features a proprietary dynamic loop compensation to maintain optimal regulation accuracy and stability. The output voltage is adjustable from 1.2V to 5V over an external resistor divider.

The ST755CN uses a peak current-mode control with integrated high voltage MOSFET for excellent response to transient loading. The device has a very low output voltage ripple and excellent loop stability even with small external ESR and ceramic capacitors. It also offers fast dynamic response and good transient load shedding. The high-performance operating frequency range is 200KHz to 1MHz and can be adjusted using an external resistor to optimize efficiency, output noise and transient response.

The primary benefit of the ST755CN is its high efficiency and small size. The high-voltage MOSFET integrated on the same die as the driver, along with the high current buffering capacity, make it a suitable choice for space-constrained applications. The low quiescent current and the PFM/PWM operating modes make the device highly power efficient. The fast loop response time and the wide output voltage range maximize flexibility and make the device suitable for a variety of applications.

The ST755CN is ideal for powering low-power, cost-sensitive, and size-constrained applications such as medical and industrial control products, digital cameras, and many other consumer and portable devices. The device offers high efficiency, low noise and fast transient response. It has built-in programmable soft-start, UVLO, short-circuit protection, and thermal shutdown features.
