Infineon Pwm Controller, 250kHz Maximum Switching Frequency, 10V Output Voltage - ICE2QS02GXUMA1


This PWM controller is a quasi-resonant device designed for efficient power supply management in various applications. With a compact PG-DSO package measuring 5 x 4 x 1.73 mm, it includes advanced features for optimising switching frequencies and enhancing performance across a range of load conditions.

Features & Benefits


• Quasi-resonant operation increases system efficiency and reduces EMI

• Built-in digital frequency reduction enhances average efficiency

• Cycle-by-cycle peak current limitation enhances safety during operation

• Adjustable blanking time ensures effective overload protection

• Short winding protection features safeguard against transformer damage

Applications


• Utilised in off-line power supply designs for LCD televisions

• Applicable in audio equipment power management systems

• Designed for use in printer power supply circuits

• Ideal for requiring an auxiliary power converter

How does the peak current limitation function in this controller?


The device incorporates cycle-by-cycle current limiting, which involves sensing the source current through a shunt resistor. If the sensed voltage exceeds a pre-set limit, the gate drive is immediately turned off, preventing potential overcurrent situations.

What protection features are included to prevent system failures?


It has multiple protection functions including adjustable overload protection, undervoltage lockout, and output overvoltage detection, which effectively ensure the system remains operational without failure during unusual conditions.

How is digital frequency reduction implemented in the design?


The controller features a digital signal processing circuit that monitors load levels, enabling it to reduce switching frequency dynamically as load conditions change, which leads to enhanced energy efficiency across varying operational states.
