1 / 32 page November 2010 Doc ID 18133 Rev 1 1/32 32 L6738 Single-phase PWM controller with light-load efficiency optimization Features ■ Flexible power supply from 5 V to 12 V bus ■ Power conversion input as low as 1.5 V ■ Light-load efficiency optimization ■ Embedded bootstrap diode ■ VIN detector ■ 0.8 V internal reference ■ 0.5 % output voltage accuracy ■ Remote GND recovery ■ High-current integrated drivers ■ Sensorless and programmable precise-OC sense across Inductor DCR ■ OV protection ■ Programmable oscillator up to 600 kHz ■ LS-less to manage pre-bias startup ■ Adjustable output voltage ■ Disable function ■ Internal soft-start ■ VFQFPN 16 3x3 mm package Applications ■ Memory and termination supply ■ Subsystem power supply (MCH, IOCH, PCI) ■ CPU and DSP power supply ■ Distributed power supply ■ General DC-DC converter Description The L6738 is a single-phase step-down controller with integrated high-current drivers that provides complete control logic and protection to realize a DC-DC converter. The device flexibility allows to manage conversions with power input VIN as low as 1.5 V and the device supply voltage ranging from 5 V to 12 V bus. The L6738 features a proprietary algorithm that allows Light-Load efficiency optimization, boosting efficiency without compromising the output voltage ripple. The integrated 0.8 V reference allows generation of output voltages with ±0.5 % accuracy over line and temperature variations. The oscillator is programmable up to 600 kHz. The L6738 provides a programmable dual level overcurrent protection and overvoltage protection. The current information is monitored across the inductor DCR. The L6738 is available in a VFQFPN 16 3x3 mm package. Table 1. Device summary Order code Package Packing L6738 VFQFPN16 Tube L6738TR VFQFPN16 Tape and reel VFQFPN16 www.st.com |
