The TPS7H502x is a radiation-hardness-assured, current mode, single-ended PWM controller with an integrated gate driver that can be utilized in both silicon and gallium nitride (GaN) power semiconductor based converter designs. The TPS7H502x integrates several key functions, such as soft-start, enable, and adjustable slope compensation while maintaining a small package size. The controller also features a 0.6V ±1% voltage reference tolerance to support highly accurate power converter designs.

The TPS7H502x can be operated using an external clock through the SYNC pin or by programming the internal oscillator using the RT pin at a frequency determined by the user. The device is capable of switching at frequencies up to 1MHz. The driver stage for the controller has a wide input voltage range from 4.5V to 14V and supports peak source and sink currents up to 1.2A. The programmable regulator, VLDO, can also be connected directly to the input of the driver stage (PVIN) in order to supply well-controlled gate voltage for operation with GaN FETs. The programmable regulator has a voltage range from 4.5V to 5.5V. The TPS7H5020 device has a maximum duty cycle of 100% while the TPS7H5021 has a 50% maximum duty cycle. The controller supports numerous power converter topologies, including flyback, forward, and boost.
