• Output Over-Voltage and Under-Voltage Latch- LM2737 can be used. Power
Off (LM2727) sequencingis achieved with
• Output Over-Voltage and Under-Voltage Flag adjustable soft-start and output
(LM2737) LM2737 and LM2737 operate 5V
bias and can convert froma 2.2Vto 16V power rail.
• Reference Accuracy: 1.5% (0°C- 125°C)Both parts utilizea fixed-frequency, voltage-mode,
• Current Limit Without Sense Resistor PWM control architecture and the switching
• Soft Start frequency is adjustable from 50kHz to 2MHz by
Switching Frequency from50 kHzto2 MHz adjusting the valueof an external resistor. Current
limit is achieved by monitoring the voltage drop
• TSSOP-14 Package across the on-resistanceof the low-side MOSFET,
which enhances low duty-cycle operation. The wide
APPLICATIONS range of operating frequencies gives the power
Cable Modems supply designer the flexibilityto fine-tune component
size, cost, noise and efficiency. The adaptive, non-
• Set-Top Boxes/ Home Gateways overlapping MOSFET gate-drivers and high-side
• DDR Core Power bootstrap structure helps to further maximize
High-Efficiency Distributed Power efficiency. The high-side power FET drain voltage can from 2.2V to 16V and the output voltageis
