TPS61010DGS, Преобразователь постоянного тока повышающий синхронный подстраиваемый 0.2А

Описание TPS61010DGS

The TPS61010DGS is a low input voltage synchronous Boost Converter with adjustable output. The boost converter intended for systems that are typically operated from a single- or dual-cell nickel-cadmium (NiCd), nickel-metal hydride (NiMH) or alkaline battery. The converter output voltage can be adjusted from 1.5V to a maximum of 3.3V, by an external resistor divider or, is fixed internally on the chip. The device provides an output current of 200mA with a supply voltage of only 0.9V. The converter starts up into a full load with a supply voltage of only 0.9V and stays in operation with supply voltages down to 0.8V. The converter is based on a fixed frequency, current mode, pulse-width-modulation (PWM) controller that goes automatically into power save mode at light load. It uses a built-in synchronous rectifier, so, no external Schottky diode is required and the system efficiency is improved. The current through the switch is limited to a maximum value of 1300mA.

• Integrated synchronous rectifier for highest power conversion efficiency (>95%)
• Power-saving mode for improved efficiency at low output current
• Auto-discharge allows to discharge output capacitor during shutdown
• Ease-of-use through isolation of load from battery during shutdown of converter
• Integrated anti-ringing switch across inductor
• Integrated low battery comparator
• <50µA Quiescent current
• Green product and no Sb/Br
