All devices offer high efficiency and ease of use. Low-resistance power switches allow up to 30A output current at high ambient temperature. The devices can operate in stacked mode to deliver higher output currents or to spread the power dissipation across multiple devices. The TPS6287x-Q1 family implements a fixedfrequency DCS-Control scheme that supports a fast transient response. The devices can operate in power-save mode for maximum efficiency or forced PWM mode for best transient...
