The SC1159SWTRT is an advanced, low cost, high performance PMIC geared towards applications in the DC/DC power conversion industry. It offers high efficiency, wide input voltage range, fast transient response and superior performance. Designed with Switched Capacitor technology, it offers a low area solution for power conversion.

The SC1159SWTRT features a wide input voltage range from 5V to 28V and is suitable for applications such as high density wall adapters, routers and media players/satellites, power supplies and lighting. It offers a wide range of features, including:

  • Output voltage range of 0.8V to 3.6V
  • Input overvoltage protection up to 36V
  • 5.5V to 28V fixed start output voltage
  • Programmable dead time and current limit
  • Low EMI/EMC performance
  • Adjustable output voltage
  • High-frequency switching up to 3MHz
  • Thermal protection circuit

The SC1159SWTRT is designed to operate with a fixed-frequency current-mode architecture. It uses a Voltage Control Oscillator (VCO) to regulate the switching frequency and a current-sense amplifier to ensure stability in applications with high load currents. Its advanced PWM switching regulator control ensures excellent load and line regulation for high efficiency and low output ripple over its entire operating range.

The DC/DC switching controller offers excellent efficiency and transient response, as well as superior protection against over-current, over-voltage and thermal stress. It is optimized for burst mode operation, meaning that it can reduce the average power consumed with short input power on-off cycles. This enables end-products to consume less power, reducing system costs and improving thermal performance.

The SC1159SWTRT also offers an adjustable output voltage that is adjustable on a per-load basis. Advanced shutdown modes allow the user to adjust the loading conditions without power cycle and provide soft-start capabilities. All these features provide the user with better control over the power supply circuit.

With its comprehensive protection, fully adjustable functions and an operating temperature range of -40°C to +85°C, the SC1159SWTRT is an ideal candidate for applications needing an efficient and cost effective power conversion solution.
