What are the key features of ICE5QR4770AZXKLA1?
- Combined current-mode and voltage-mode PWM control enables flexible AC/DC flyback converter topologies with a single IC
- Input voltage range of 11 V to 27 V (nominal 18 V) covers typical auxiliary supply rails in offline power supply designs
- Integrated CoolSET DP Lite architecture reduces external component count and PCB area versus discrete controller solutions
- DIP-7 package (R-PDIP-T7) simplifies prototyping and through-hole assembly for industrial and consumer power supply boards
What is ICE5QR4770AZXKLA1 used for?
The ICE5QR4770AZXKLA1 is used as the primary controller in offline flyback AC/DC power supplies for industrial equipment, set-top boxes, and consumer electronics chargers. Its combined current/voltage-mode PWM control supports quasi-resonant switching designs that reduce switching losses and EMI at power levels up to tens of watts. The wide 11 V to 27 V input range also suits auxiliary supply controller applications within multi-rail industrial and telecom power systems.

Frequently Asked Questions
What input voltage range does the ICE5QR4770AZXKLA1 support, and what nominal bias voltage does it require?
The ICE5QR4770AZXKLA1 operates with an input voltage range from 11 V minimum to 27 V maximum, with a nominal operating voltage of 18 V. This range covers the auxiliary winding voltages typical in offline flyback converters, allowing the IC to self-power from the transformer's bias winding without a separate regulator.
Which converter topology and control method does the ICE5QR4770AZXKLA1 use?
The ICE5QR4770AZXKLA1 implements pulse width modulation (PWM) using combined current-mode and voltage-mode control, which is well-suited to flyback and forward converter topologies used in AC/DC offline power supplies. The CoolSET DP Lite architecture integrates the controller and sense functions, reducing external component count compared to discrete PWM designs.
When comparing the ICE5QR4770AZXKLA1 to a fully integrated CoolSET device, what trade-off should designers consider?
The ICE5QR4770AZXKLA1 DP Lite variant pairs the PWM controller with an external FET rather than an integrated switch, giving designers the flexibility to select a power MOSFET matched to their specific 11 V–27 V input and load current requirements, at the cost of 1–2 additional components versus a fully monolithic CoolSET device. This trade-off suits designs where output power or voltage rating exceeds what fully integrated options provide.
