N2 - This paper presents the design of a compact Power Management Integrated Circuit (PMIC) utilizing 650 V Enhancement-mode (E-mode) p-GaN technology for medium power Electric Vehicles (EV) charging applications. The proposed PMIC achieves Integration Level 3 by incorporating a Pulse Width Modulation (PWM) generator, a two-stage fast gate driver, a high-voltage power switch, and a current-mirror sensor. Post-layout simulations conducted in Cadence Virtuoso assess the circuit's performance under varying temperature conditions. The PMIC operates at 1 MHz, with an output power of 1 kW and 97% of efficiency. The PWM generator features a wide controllability range from 5% to 95% duty cycle, while the gate driver achieves rise and fall times of 9.45 ns and 14.5 ns, respectively. The total active area, including pads, measures 2.94mm2
