The TPS61020 is a highly integrated, low-power, boost converter ideally suited for portable battery-powered equipment. To improve start-up performance from a power-limited source such as a battery, the TPS6102x family uses different steps and modes to reduce demand on the battery. This prevents the battery bus from sagging during start-up and improves start-up operation at low voltage. - How to Choose the Appropriate TPS6107x for your ApplicationPDF, 87 Kb, Datei veröffentlicht: Feb 27, 2007
