The ADP1621 is a fixed-frequency, pulse-width modulation (PWM), current-mode, step-up converter controller. It drives an external n-channel MOSFET to convert the input voltage to a higher output voltage. The ADP1621 can also be used to drive flyback, SEPIC, and forward converter topologies, either isolated or nonisolated. The ADP1621 eliminates the use of a current-sense power resistor by measuring the voltage drop across the on resistance of the n-channel MOSFET. This technique, allowed up to a maximum voltage of 30 V at the switch node, maximizes efficiency and reduces cost. For switch-node voltages higher than 30 V or for more accurate current limiting, the CS pin can be connected to a current-sense resistor in the source of the MOSFET. The slope compensation is implemented by an external resistor, allowing a wide range of external components (inductors and MOSFETs), and can be chosen for various switching frequencies and input and output voltages. The ADP1621 supply input voltage range is 2.9 V to 5.5 V, although higher input voltages are possible with the use of a small-signal NPN pass transistor or a single resistor. The voltage of the power input can be as low as 1 V for fuel cell applications. The switching frequency is set by an external resistor over a range of 100 kHz to 1.5 MHz and can be synchronized to an external clock by using the SDSN pin. The shutdown quiescent current is less than 10 μA. The ADP1621 has a thermal shutdown feature that shuts down the gate driver when the junction temperature reaches approximately 150°C. The internal soft start circuit limits inrush current at startup. The ADP1621 is available in the 10-lead MSOP lead-free package and is specified over the −40°C to +125°C junction temperature range.

ADP1621 DC-to-DC Controller
Analog Devices ADP1621 DC-to-DC Controller is offered as a fixed-frequency, pulse-width modulation (PWM), current-mode, step-up converter controller with a 92% efficiency rating and ±1% initial accuracy. The ADP1621 Controller drives an external N-channel MOSFET to convert the input voltage to a higher output voltage. The device uses lossless current sensing for switch-node voltage <30V and resistor current sensing for switch-node voltage >30V. Designers can use the ADP1621 Controller to drive SEPIC, flyback, and forward converter topologies. The ADP1621 Controller operates using a 2.9V-5.5V IC supply input voltage. Higher input voltages (>5.5V) are achievable with the use of a small signal NPN pass transistor or a single resistor. The device allows a power input voltage as low as 1V for fuel cell applications. Designers can use an external resistor to set the switching frequency over a 100kHz-1.5MHz range. The SDSN pin synchronizes the switching frequency to an external clock. ADP1621's input supply current is less than 3mA during normal operation and less than 10μA during shutdown. The design of the  ADP1621 Controller allows thee device to drive large external MOSFETs and support load currents above 10A.Learn More
