Linear Technology LTC1702

The LTC1702 uses a constant-frequency, true PWM design switching at 550kHz, minimizing external component size and cost and maximizing load transient performance. The synchronous buck architecture automatically shifts to discontinuous and then to Burst ModeTM operation as the output load decreases, ensuring maximum efficiency over a wide range of load currents. The LTC1702 features an onboard reference trimmed to 0.5% and can provide better than 1% regulation at the converter outputs.
