TPS62110RSATG4

The TPS62110RSATG4 is a 17V Vin Synchronous Step-down Converter ideally suited for systems powered from a 2- to 4-cell Li-ion battery or from a 12 or 15V rail. The TPS62110 device is synchronous pulse width modulation (PWM) converter with integrated N- and P-channel power MOSFET switches. Synchronous rectification is used to increase efficiency and to reduce external component count. To achieve highest efficiency over a wide load-current range, the converter enters a power-saving, pulse frequency modulation (PFM) mode at light load currents. Operating frequency is typically 1MHz, allowing the use of small inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 0.8 to 1.4MHz. For low-noise operation, the converter can be operated in PWM-only mode. In shutdown mode, the current consumption is reduced to less than 2µA.

• 20µA Typical quiescent current
• Over-temperature and over-current protected
• Green product and no Sb/Br

警告

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
