Infineon ICE3PCS01GXUMA1, Power Factor Controller IC 250 kHz 14-Pin, DSO 25V

Infineon Series IC Power Factor Controller IC, 250kHz Switching Frequency, 14 Pin Count - ICE3PCS01GXUMA1

This power-factor controller IC is a surface-mount device designed to manage power-factor correction in electronic power supplies. It operates across a wide temperature range and targets industrial applications that require compact PFC control with low quiescent supply demand and defined switching behaviour.

Features and Benefits:

• Low start-up supply current reduces auxiliary power requirements
  Switching-frequency setpoint enables high-speed PFC operation
  Operates from low to high supply voltages, enhancing design headroom
  Negative source-current capability supports specific gate-drive needs
  Wide operating temperature range allows deployment in harsh environments

Applications

• Suitable for industrial power-supply PFC front ends
  Ideal for high-frequency converter designs requiring compact controllers
  Used with surface-mount power stages on dense assemblies
  Can be used for thermally stable systems in elevated-temperature sites

What are the device pin count and package type for PCB layout?

It is offered in a 14-pin DSO package intended for surface mounting, facilitating dense PCB layouts.

What supply conditions should the designer consider for start-up?

Designers should allow for a start-up supply current of 2.4 mA when sizing auxiliary power and sequencing circuits.

How does thermal capability affect placement near heat sources?

The component is rated to a maximum operating temperature of 150°C and a minimum of -40°C, so placement close to hot components must respect that upper limit for reliable operation.

What switching characteristic is provided for EMI and filtering planning?

The device uses a switching frequency of 250 kHz, which informs inductor selection and EMI filter design.
