uP1539 - Single Phase PWM Controller

Key Features

  • The uP1539 is a single phase PWM controller with integrated high-current MOSFET driver. It can work with either 5V or 12V supplies and converts 1.5V to 19V power input. The bootstrap diode is built-in to simplify the circuit design and minimize external part count. The uP1539 implements voltage mode control loop with fast transient response. High light-load efficiency is achieved by the single control loop. The operation frequency is programmable up to 1000kHz. The uP1539 provides a programmabl.

uP1539 Single Phase PWM Controller with Light-Load Efficiency Optimization General Description Features The uP1539 is a single phase PWM controller with integrated high-current MOSFET driver. It can work with either 5V or 12V supplies and converts 1.5V to 19V power input. The bootstrap diode is built-in to simplify the circuit design and minimize external part count. The uP1539 implements voltage mode control loop with fast transient response. High light-load efficiency is achieved by the single control loop. The operation frequency is programmable up to 1000kHz. The uP1539 provides a programmable dual level overcurrent protection. The current information is monitored across the inductor DCR. Other features include pre-bias internal soft-start, power OK indication, UVP, OVP and OTP.
