What are the key features of UC2874DW-2?
- Dual-mode current/voltage-mode PWM control providing flexibility to optimize loop stability for both continuous and discontinuous conduction mode power stages
- Wide 10 V to 36 V input voltage range with 12 V nominal operation covering standard 12 V and 24 V industrial bus voltages without additional pre-regulation
- 18-pin SOIC package (R-PDSO-G18) with JESD-609 e4 Pb-free compliance enabling RoHS-compatible SMD assembly in industrial and telecom power designs
- Dual-controller architecture allowing two independent PWM channels to be driven from a single IC, reducing BOM count in multi-rail power supply systems
What is UC2874DW-2 used for?
The UC2874DW-2 is used in industrial power supplies, distributed power architectures, and telecom equipment where two independent high-efficiency DC-DC converter channels must be controlled from a single IC. Its current-mode and voltage-mode flexibility enables design engineers to select the optimal control topology for their specific output requirements, including point-of-load converters for FPGAs, DSPs, and communication ASICs. The device is also applied in motor drive auxiliary supplies and embedded computing platforms requiring regulated outputs from 12 V or 24 V input bus rails.

Frequently Asked Questions
What control modes does the UC2874DW-2 support?
The UC2874DW-2 supports both current-mode and voltage-mode PWM control, giving power supply designers the flexibility to select the optimal loop compensation and transient response characteristics for their specific DC-DC converter topology and load conditions.
What is the input voltage range of the UC2874DW-2?
The UC2874DW-2 operates from a 10 V minimum to 36 V maximum input, with a 12 V nominal supply voltage. This range covers standard 12 V and 24 V distribution buses used in industrial automation, telecom infrastructure, and embedded computing systems.
What package does the UC2874DW-2 use?
The UC2874DW-2 is packaged in an 18-pin wide-body SOIC (R-PDSO-G18) surface-mount package, offering a compact footprint compatible with standard SMD pick-and-place and reflow soldering equipment used in industrial and commercial power supply manufacturing.
Can the UC2874DW-2 control two separate power conversion channels?
Yes, the UC2874DW-2 integrates two independent DC-DC switching controller channels, allowing a single device to manage two separate output rails simultaneously. This reduces total component count and PCB area compared to using two discrete single-channel controllers in a multi-output power supply.
What are typical applications for the UC2874DW-2?
Typical applications include point-of-load DC-DC converters for FPGA and DSP power rails, distributed power systems in telecom racks, motor drive auxiliary power supplies, and industrial control cards where efficient PWM-controlled power conversion from a 12 V or 24 V bus is needed with dual independent output channels.
