The CS5165H is a 5-bit synchronous buck controller from Infineon that features a V2™ control architecture with a 100ns fastest transient response and the industry’s best overall voltage regulation. Its feature-rich design gives end users maximum flexibility to implement the best price/performance solutions for their end products.
The Cherry Semiconductor CS5165H is a synchronous 5-bit NFET buck controller designed to manage power for next-generation Pentium II processors. It features a unique V2 control architecture that delivers the fastest transient response in the industry at 100ns, along with superior voltage regulation.
The device includes an on-board 5-bit DAC with +1% tolerance over temperature and a programmable soft-start circuit to ensure controlled startup. It also incorporates FET non-overlap circuitry to prevent simultaneous conduction of both MOSFETs. The controller supports operation from single or dual 5V/12V power supplies and includes protection features such as Overvoltage Protection (OVP) and short-circuit hiccup mode.
| Transient Response | 100ns |
|---|---|
| Operating Junction Temperature Range | -65°C to 150°C |
| Package Type | 16 Lead SOIC Wide Body |
| Supply Voltage Range | 5V and 12V |
| DAC Accuracy | +1% tolerance over temperature |
No, the OVP feature is part of the V2 architecture and does not require any additional components.
During a short circuit, the controller pulses the MOSFETs in a 'hiccup' mode with an 8% duty cycle until the fault is removed.
