The step- Reduced EMI down converter enters a low-power mode at light load for maximum efficiency across the widest possible – 2.25-MHz Fixed Frequency Operation range of load currents. For low-noise applications, the – 600-mA or 1-A (TPS650061) Output Current devices can be forced into fixed-frequency PWM • Low Dropouts (LDOs): through a pin. The step-down converter is small because of its small inductor and capacitors. The – VIN Range From 1.6 V to 6 V step-down converter has power good status output – Adjustable Output Voltage for sequencing. The LDOs can supply 300 mA and – Up to 300-mA Output Current operate with an input voltage range from 1.6 V to 6 V. A step-down converter or main battery can power the – Separate Power Inputs and Enables LDOs directly. The step-down converter and the • Supply Voltage Supervisor (TPS65001) LDOs have separate voltage inputs that enable – Manual Reset Input for Push Button maximum design and sequencing flexibility. – Adjustable Reset Time Device Information(1) – Adjustable Reset Voltage PART NUMBER PACKAGE BODY SIZE (NOM) • 3-mm × 3-mm 16-Pin WQFN (TPS65000) TPS65000, • 3-mm × 3-mm 20-Pin WQFN (TPS65001) TPS650001, WQFN (16) 3.00 mm × 3.00 mm TPS650003, TPS650006 2 Applications TPS65001, WQFN (20) 3.00 mm × 3.00 mm • Points-of-Load TPS650061 • Embedded Processor Power (1) For all available packages, see the orderable addendum at the end of the data sheet. • Cell Phones • Smart Phones • PDAs • Pocket PCs • Portable Media Players Application Circuit 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
