概要
Description
LT8336EV#PBF is Linear Technology/Analog Devices’ evaluation board for the LT8336 DC-DC controller. It provides a ready-to-use platform to evaluate the LT8336’s performance in a practical buck/buck-boost-type application over a wide input range. The board includes the necessary support circuitry (external MOSFETs, inductor, diodes, sense and compensation networks), plus convenient test points, input/output connectors, and a trim potentiometer to set the output voltage. It demonstrates key performance aspects such as high efficiency, good line/load regulation, fast transient response, and built‑in protection features (over-current, over-voltage, short-circuit protection, thermal shutdown). You can modify component values or feedback networks to explore different operating points or topologies. The EV board is Pb-free (PBF) and intended for laboratory evaluation and bench testing. For final designs, consult the LT8336 data sheet and application notes for detailed design guidelines.
Equivalent
LT8336EV#PBF is a 60 V input buck‑boost LED driver with integrated FETs. There isn’t an exact one‑for‑one cross. Closest non‑LT options: TI LM5170/LM5171 buck‑boost LED controllers (60 V input); ON Semiconductor NCP81239 (60 V buck‑boost LED driver); STMicroelectronics LED‑driver families (topology depending). For a precise replacement, use a distributor cross‑reference tool or consult Analog Devices.
Features
LT8336EV#PBF is the evaluation board for the LT8336 four‑switch, synchronous buck/boost controller. Key features:
- Wide input range with buck, boost, and buck‑boost operation
- Integrated high‑ and low‑side MOSFETs (four‑switch topology)
- Current‑mode control with slope compensation
- Programmable switching frequency with external compensation options
- Adjustable output voltage via resistor divider; remote sense available
- Soft‑start and Power‑Good signaling
- Protections: overcurrent/short‑circuit with hiccup, overvoltage/UVLO, thermal shutdown
- High efficiency across wide load ranges
- Evaluation board with standard input/output connectors, built‑in inductor, sense resistors, input protection, and test points for loop compensation and measurements
Note: exact voltage/current specifications depend on the chosen configuration; refer to LT8336 datasheet and EV board schematics for precise values.
