Infineon Technologies Analog POL regulator family

20 A, 12 A fully integrated and highly efficient DC-DC buck regulator family using fast constant-on-time (COT) control scheme. Simplifies design efforts and achieves fast transient response while maintaining excellent line and load regulation. It can operate over a wide range of Vin (2.7 V to 16 V) and support Vout from 0.6 V to 5.5 V.

Key features

• Precision reference voltage (0.6 V +/- 0.5%)
• Stable with ceramic output capacitors
• No external compensation
• Selectable switching freq from 600 kHz, 800 kHz, and 1 MHz

Additional features

• Wide Vin range: 4 V to 16 V with internal bias and 2.7 V to 16 V with external V_CC (3.3 V)
• Optional forced continuous conduction mode and diode emulation for enhanced light load efficiency
• Programmable soft-start time with a min of 1 ms & enhanced pre bias start-up
• Voltage tracking with external reference input
• Programmable over current protection limit with internal thermal compensation
• Enable input with voltage monitoring capability
• Power good output
• Non-latch OCP, UVP, thermal shutdown, and Latch-off OVP
• Operating temp: -40°C < Tj < 125°C
• Small size: 3 mm x 4 mm QFN-21
• Lead-free, halogen-free and RoHS compliant
