CJ9217 1.5A, 2V-5.5V Input, 1.5MHz Synchronous Step-Down Converter

PublishTime： 2020-09-30 Manufacturer： JSCJ

The CJ9217 is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture.The device is available in an adjustable version. Supply current with no load is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makes the CJ9217 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM/PFM mode operation provides very low output ripple voltage for noise sensitive applications.Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage.

2A/18V Synchronous Step-Down Converter SY8120B with 600KHz Switching Frequency

2024-01-26 - Product Introduction The SY8120B are high efficiency 600KHz synchronous step-down DC-DC converters capable of delivering 2.0A output currents, respectively. SY8120B operate over a wide input voltage range from 4V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor sizes are achieved with 600KHz switching frequency.
