.ti. SNVS152C - MAY 2001 - REVISED MARCH 2013 LM2700 600k Hz/1.25MHz, 2.5A, Step-up PWM DC/DC Converter Check for Samples: LM2700 Features - 2 3.6A, 0.08Ω, Internal Switch - Operating Input Voltage Range of 2.2V to 12V - Input Undervoltage Protection - Adjustable Output Voltage up to 17.5V - 600k Hz/1.25MHz Pin Selectable Frequency Operation - Over Temperature Protection - Small 14-Lead TSSOP or WSON Package APPLICATIONS - LCD Bias Supplies - Handheld Devices - Portable Applications - GSM/CDMA Phones - Digital Cameras DESCRIPTION The LM2700 is a step-up DC/DC converter with a 3.6A, 80mΩ internal switch and pin selectable operating frequency. With the ability to produce 500m A at 8V from a single Lithium Ion battery, the LM2700 is an ideal part for biasing LCD displays. The LM2700 can be operated at switching frequencies of 600k Hz and 1.25MHz allowing for easy filtering and low noise. An external pensation pin gives the user flexibility in setting frequency pensation, which makes possible the use of small, low ESR ceramic capacitors at the output. The LM2700 Features continuous switching at light loads and operates with a switching quiescent current of 2.0m A at 600k Hz and 3.0m A at 1.25MHz. The LM2700 is available in a low profile 14-lead TSSOP package or a 14-lead WSON package.
