A4403GEUTR-T

The A4403GEUTR-T is a valley current mode control Buck Converter with an extremely fast load-transient response with minimal output voltage delta. The current mode control scheme allows very short switch on-times to be achieved, making it ideal for applications that require high switching frequencies combined with high input voltages and low output voltages. The switching frequency is maintained constant, as the on-time is modulated by the input voltage. This feed-forward control ensures excellent line correction. The on-time is set by an external resistor pulled-up to the input supply.

• Extremely fast load-transient response with minimal output voltage delta
• Achieves high step-down ratios with on-times <lt/>50ns
• User-configurable on-time, achieving switching
• Minimal external components required
• -40 to 105°C Ambient temperature range
