IP1001

Voltage Regulators - DC DC Switching Regulators Overview

The IP1001 is a fully optimized synchronous buck power block designed for high-current applications requiring up to 20A. It integrates a fast transient response PWM controller, an optimized power semiconductor chip-set, and associated passives into a single module. The device supports an input voltage range of 3.3V to 12V and offers an adjustable output voltage between 0.925V and 2V via a 5-bit DAC. It operates at nominal switching frequencies of 200kHz or 300kHz. The component features overvoltage protection, undervoltage protection, and adjustable lossless current limit within a compact 14mm x 14mm x 3mm outline.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates full-function PWM control with optimized power semiconductors and passives for benchmark power density
• Supports configurable operation down to 3.3V input using simple external boost circuits
• Includes internal features that minimize layout sensitivity and reduce the requirement for external components

Voltage Regulators - DC DC Switching Regulators Applications

• High current synchronous buck applications
• Single-phase power conversion systems
• Systems requiring very low power losses and fast transient response

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors as the IP1001 is listed as obsolete. Confirm RoHS compliance status, which is noted as non-compliant in some records. Check for availability of original International Rectifier documentation versus Infineon archives. Ensure design-in compatibility with existing thermal management solutions given the 20A capability and small form factor.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs prioritizing high power density and reduced bill of materials due to integrated passives. Consider the need for external boost circuitry if input voltages drop below 3.3V. Evaluate thermal performance requirements carefully, as the device supports 20A without derating only up to specific PCB temperatures. Verify that the 0.925V to 2V output range meets system load requirements.
