Description

The TPS62003DGS is a Step-down DC/DC Converter ideally suited for systems powered from a 1-cell Li-ion battery or from a 2- to 3-cell NiCd, NiMH or alkaline battery. It operates typically down to an input voltage of 1.8V, with a specified minimum input voltage of 2V. It operate in a current mode PFM/PWM scheme with a typical switching frequency of 750kHz. At moderate to heavy loads, the converter operates in the pulse width modulation (PWM) and at light loads the converter enters a power save mode (pulse frequency modulation, PFM) to keep the efficiency high. In the PWM mode operation, the part operates at a fixed frequency of 750kHz. At the beginning of each clock cycle, the high side P-channel MOSFET is turned on. The current in the inductor ramps up and is sensed via an internal circuit. The high side switch is turned off when the sensed current causes the PFM/PWM comparator to trip when the output voltage is in regulation or when the inductor current reaches the current limit.
High-efficiency synchronous step-down converter with more than 95% efficiency
Synchronizable to external clock signal up to 1MHz
Pin-programmable current limit
High efficiency over a wide load current range in power save mode
100% Maximum duty cycle for lowest dropout
Low-noise operation antiringing switch and PFM/PWM operation mode
Internal soft-start
Green product and no Sb/Br
