What is LM2619MTC used for?
LM2619MTC provides regulated step-down conversion for cellular handset subsystems, portable media players, and handheld GPS units powered from single lithium-ion cells with 2.8 V to 5.5 V input voltage. Its adjustable output voltage and 500 mA current capability support DSP core rails, SRAM, and display driver supply lines in compact mobile PCB designs. The current-mode PWM architecture ensures fast transient response to sudden load steps common in RF transmitter and backlight activation events.

Frequently Asked Questions
What maximum output current does LM2619MTC support and which mobile subsystems can it power?
LM2619MTC delivers up to 500 mA continuous output current, sufficient to power DSP cores, SRAM arrays, LCD display drivers, and Bluetooth modules in portable handsets. At 3.6 V input and 1.8 V output, the 500 mA capability covers typical DSP active current draws in narrowband LTE and GPS receiver circuits.
How does the current-mode PWM architecture of LM2619MTC improve transient response in mobile designs?
Current-mode PWM control in LM2619MTC senses inductor current on every switching cycle, allowing the regulator to respond to load transients within 1 to 2 switching cycles rather than waiting for output voltage error to propagate through a voltage-mode loop. This fast response limits output voltage deviation to typically less than 50 mV during RF transmitter power-up or backlight activation steps.
Over what input voltage range does LM2619MTC operate and which battery types are compatible?
LM2619MTC accepts input voltages from 2.8 V to 5.5 V, covering the full discharge range of single-cell lithium-ion (3.0 V to 4.2 V) and lithium-polymer batteries. The 5.5 V maximum also supports USB bus-powered operation, allowing LM2619MTC to regulate consistently from both battery and wired charging sources without external switching.
Is LM2619MTC suitable for a compact two-layer PCB design in a handheld device?
Yes. The 14-pin TSSOP package with 0.65 mm pitch keeps the regulator footprint under 25 mm² including bypass capacitors and a 1 µH to 4.7 µH inductor. Current-mode control allows use of smaller output capacitors (10 µF ceramic), and the switching frequency of approximately 1.5 MHz reduces inductor size, making LM2619MTC practical for 2-layer mixed-signal PCBs in handheld consumer electronics.
