Product Overview
LTC®1624 is a current mode switching regulator controller that drives an external N-channel power MOSFET using a fixed frequency architecture. It can be operated in all standard switching configurations including boost, step-down, inverting and SEPIC. Burst Mode™ operation provides high efficiency at low load currents. A maximum high duty cycle limit of 95% provides low dropout operation which extends operating time in battery-operated systems. The operating frequency is internally set to 200KHz, allowing small inductor values and minimizing PC board space. The operating current level is user-programmable via an external current sense resistor. A multifunction pin (ITH /RUN) allows external compensation for optimum load step response plus shutdown. Typical applications are notebook and palmtop computers, PDAs, cellular telephones and wireless modems, battery-operated digital devices, DC power distribution systems, battery chargers.
- N-channel MOSFET drive, implements boost, step-down, SEPIC and inverting regulators
- Wide VIN range: 3.5V to 36V operation, wide VOUT range: 1.19V to 30V in step-down configuration
- ±1% 1.19V reference, low dropout operation: 95% duty cycle
- 200KHz fixed frequency, low standby current, very high efficiency
- Remote output voltage sense, logic-controlled micropower shutdown
- Current mode operation for excellent line and load transient response
- Internal diode for bootstrapped gate drive
- Feedback current is 50nA, feedback voltage range from 1.178 to 1.201V (TA=25°C, VIN=15V)
- 8-lead plastic SO package
- Operating temperature range from –40°C to 85°C
