LM2716 is a dual-path DC/DC converter from National Semiconductor. It consists of a fixed output voltage buck converter and an adjustable output voltage boost converter. Both use low RDSON (0.16 Ω and 0.12 Ω) internal switches for maximum efficiency. The operating frequency can be adjusted anywhere between 300 kHz and 600 kHz, allowing the use of small external components. External soft-start pins for each allow the user to tailor the soft-start times to a specific application. Each converter may also be shut down independently with its own shutdown pin. The LM2716 is available in a low profile 24-lead TSSOP package.
The LM2716 is a dual PWM DC/DC converter that combines a fixed‑output buck (step‑down) stage with an adjustable‑output boost (step‑up) stage. Both converters use low‑on‑resistance internal switches for high efficiency and offer independent soft‑start and shutdown pins. The device operates over a wide frequency range (300 kHz‑600 kHz) and is supplied in a compact 24‑lead TSSOP package.
The datasheet provides ordering information for the MT‑24 package, pin descriptions, absolute maximum ratings, electrical characteristics, and typical performance curves. Application sections show typical circuits for TFT‑LCD displays, handheld devices, and cellular phones, along with PCB layout guidance and physical dimensions.
