The LTC3708 PWM controller is described, which achieves high efficiency and fast transient response with a compact size. Its features make it an ideal controller for high performance power management applications.
High efficiency, fast transient response and small size are often at odds in power supply designs. Fortunately, the 2-phase LTC3708 PWM controller makes it possible to simultaneously achieve all three. Figure 146.1 show the LTC3708 in a compact, high efficiency dual-output power supply that has excellent transient response.
