Frequently Asked Questions
What is the operating input voltage range of the UC2825DW?
The UC2825DW operates with an input voltage range of 8.8V minimum to 12V maximum, with a nominal supply voltage of 15V. An undervoltage lockout (UVLO) circuit prevents operation below the startup threshold, ensuring reliable power-up behavior.
What switching topologies does the UC2825DW support?
The UC2825DW supports multiple switching power supply topologies including boost, flyback, full-bridge, and half-bridge configurations. Its dual 1.5A totem-pole output drivers and programmable dead-time control make it flexible for a wide range of DC-DC converter designs.
What is the maximum switching frequency of the UC2825DW?
The UC2825DW features a programmable oscillator that can be configured for switching frequencies up to 1MHz. Higher switching frequencies allow the use of smaller passive components such as inductors and capacitors, reducing overall power supply size and cost.
What package does the UC2825DW come in, and is it RoHS compliant?
The UC2825DW is available in a 16-pin SOIC (Small Outline IC) package. It is RoHS compliant with a lead-free (Pb-free) construction, suitable for use in environmentally sensitive and export-regulated applications.
