Step Down Controller

www.DataSheet4U.com SP6127 High-Voltage, Step-Down Controller in TSOT6 FEATURES Wide 4.5V – 29V Input Voltage Range Internal compensation Built-in High-Current PMOS Driver Adjustable Overcurrent Protection Internal soft start 900kHz Constant Frequency Operation 0.6V Reference Voltage 1% output setpoint accuracy Lead Free, RoHS Compliant Package: Small 6-pin TSOT LX GND FB 6 5 4 SP6127 6 PinTSOT 1 VIN 2 GATE 3 VDR __________________________________________________________ DESCRIPTION The SP6127 is a PWM controlled step down (buck) voltage mode regulator with VIN feedforward and internal Type-II compensation. It operates from 4.5V to 29V VIN, making it suitable for 5V, 12V and 24V applications. By using a PMOS driver, this device is capable of operating at 100% duty cycle. The highside driver is designed to drive the gate 5V below VIN. The programmable overcurrent protection is based on the high-side MOSFET’s ON resistance sensing and allows setting the overcurrent protection value up to 300mV threshold (measured between VIN-LX). The SP6127 is available in a space-saving 6pin TSOT package making it the smallest controller available capable of operating from 24VDC supplies. _______________________________________ TYPICAL APPLICATION CIRCUIT VIN Q1 Si2343DS 2 1 Vin Rs=1k LX C7 0.1uF 6 L1, IHLP-2525CZ 3.3uH, 30mOhm, 6A Gate C1 4.7uF 12V GND VOUT C4 22uF R1 200k, 1% 4 CZ 33pF R2 100k, 1% D1 1N4148 SP6127 3 VDR Ds MBRA340T3G RZ 2K 1.8V 0-2.0A VFB GND 5 SHDN High.
