Frequently Asked Questions
What input voltage range does LM2735YMY support and which battery chemistries are compatible?
The LM2735YMY operates from a 2.7 V to 14 V input range, making it compatible with single-cell Li-ion batteries (2.7 V to 4.2 V), two AA alkaline cells (about 2 V to 3 V nominal), and regulated 5 V or 12 V bus supplies. This flexibility covers a broad range of portable and battery-powered system designs.
How does the 1.6 MHz switching frequency of LM2735YMY benefit PCB component sizing?
At 1.6 MHz switching frequency, the LM2735YMY allows use of inductors as small as 2.2 µH to 10 µH and ceramic capacitors below 10 µF, significantly reducing external component size and cost. Higher frequency reduces ripple filter requirements and enables a total solution area under 25 mm² in compact boost converter designs.
What output current can LM2735YMY deliver and how does it affect LED driver circuit design?
The LM2735YMY integrates a 500 mA internal switch, enabling boosted output currents suitable for driving multiple series or parallel LEDs. In a typical white LED driver application stepping up from 3.6 V to 5 V, it can deliver over 200 mA output at high efficiency, requiring only a small inductor, diode, and output capacitor.
Why choose LM2735YMY in a SOT-23-5 package for space-constrained handheld designs?
The LM2735YMY SOT-23-5 package measures approximately 3 mm × 1.75 mm, occupying minimal PCB area. Combined with its 1.6 MHz switching frequency allowing miniature passives, the total boost converter footprint can fit within 30 mm². This makes it ideal for handheld medical devices, wearables, and compact IoT nodes with strict size budgets.
